Factors of 34 Definition

When we talk about the factors of 34, what we really mean is all of the positive and negative integers (whole numbers) that can be evenly divided into 34. If you were to take 34 and divide it by one of its factors, the answer would be another factor of 34.

Let's look at how to find all of the factors of 34 and list them out.

How to Find the Factors of 34

We just said that a factor is a number that can be divided equally into 34. So the way you find and list all of the factors of 34 is to go through every number up to and including 34 and check which numbers result in an even quotient (which means no decimal place).

Doing this by hand for large numbers can be time consuming, but it's relatively easy for a computer program to do it. Our calculator has worked this out for you. Here are all of the factors of 34:

34 ÷ 1 = 34
34 ÷ 2 = 17
34 ÷ 17 = 2
34 ÷ 34 = 1

All of these factors can be used to divide 34 by and get a whole number. The full list of positive factors for 34 are:

1, 2, 17, and 34

Negative Factors of 34

Technically, in math you can also have negative factors of 34. If you are looking to calculate the factors of a number for homework or a test, most often the teacher or exam will be looking for specifically positive numbers.

However, we can just flip the positive numbers into negatives and those negative numbers would also be factors of 34:

-1, -2, -17, and -34

How Many Factors of 34 Are There?

As we can see from the calculations above there are a total of 4 positive factors for 34 and 4 negative factors for 34 for a total of 8 factors for the number 34.

There are 4 positive factors of 34 and 4 negative factors of 34. Wht are there negative numbers that can be a factor of 34?

Factor Pairs of 34

A factor pair is a combination of two factors which can be multiplied together to equal 34. For 34, all of the possible factor pairs are listed below:

We have also written a guide that goes into a little more detail about the factor pairs for 34 in case you are interested!

Just like before, we can also list out all of the negative factor pairs for 34:

-1 x -34 = 34
-2 x -17 = 34

Notice in the negative factor pairs that because we are multiplying a minus with a minus, the result is a positive number.

So there you have it. A complete guide to the factors of 34. You should now have the knowledge and skills to go out and calculate your own factors and factor pairs for any number you like.

Multiplication and division are two important operations in mathematics. We can multiply a number by any number. Similarly, a number can be divided by any number. Two important terms that are related to the multiplication and division of numbers are factors and multiples. Let us learn more about factors of 34.

Definition

A factor of a number is an exact divisor of that number. In other words, a factor of a number is that number that completely divides the number without leaving a remainder. Therefore, factors of 34 would be those numbers that exactly divide the number 34. Let us learn more about these numbers which are factors of 34.

What are the factors of 34?

The factors of the number 34 are – 1, 2, 17 and 34. We can see that there are only 4 factors of the number 34. This means that there are only 4numbers that divide the number 34 completely without leaving any remainder.

How to verify factors of 34?

Let us now verify the factors of 34.

We shall use the division method for finding the factor of 34

Division by 1

Let us first divide 34 by 1. We know that every number is divisible by 1. So, 1 is a factor of 34. . . . . . . . . . . . . . . . . . . . . ( 1 )

Division by 2

Let us divide 34 by 2. We will have,

34 ÷ 2 = 17

This means that 34 is completely divided by 2 giving a quotient 17 and remainder 0 hence 2 is a factor 34. . . . . . . . . . . . . . . . . . . . . . . . . ( 2 )

So, we have 2 x 17 = 34

Now let us find the factors of 17

Division of 17

We know that 17 is a prime number. This means that there are only two factors of 17, namely 1 and the number 17 itself. Hence, it cannot be further divided into smaller factors. This marks the end of the division for finding the factors of 34. . . . . . . . . . . . . . . . . . . . ( 3 )

From ( 1 ), ( 2 ) and ( 3 ), we have,

The factors of 34 are 1, 2, 17 and 34

Using the Divisibility rule for finding the factors of 34

We know that we have a defined set of divisibility rules that allow checking to check whether a number is a factor of another number or not. Let us use these divisibility rules to verify the factors of 34.

Divisible by	Divisibility Rule	Is 34 divisible by this number?	Reason
2	If a number is even or a number whose last digit is an even number i.e. 2,4,6,8 including 0, it is always completely divisible by 2.	Yes	34 is an even number
3	The divisibility rule for 3 states that a number is completely divisible by 3 if the sum of its digits is divisible by 3.	No	3 + 4 = 7 and 7 is not divisible by 3.
4	If the last two digits of a number are divisible by 4, then that number is a multiple of 4 and is divisible by 4 completely.	No	34 only 2 digits, and hence, 34 is not divisible by 4.
5	Numbers, which last with digits, 0 or 5 are always divisible by 5.	No	34 ends with 4, not 0 nor 5.
6	Numbers which are divisible by both 2 and 3 are divisible by 6. That is, if the last digit of the given number is even and the sum of its digits is a multiple of 3, then the given number is also a multiple of 6.	No	34 is divisible by 2 but not by 3.
7	The divisibility rule of 7 states that if we get a difference that is also divisible by 7 by subtracting the last digit’s number and 2’s product, then the number is divisible by 7	No	34’s last product is 17 which is not divisible by 7
8	If the last three digits of a number are divisible by 8, then the number is completely divisible by 8.	No	34 is not divisible by 8
9	The rule for divisibility by 9 is similar to the divisibility rule by 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.	No	3 + 4 = 7 and 7 is not divisible by 9.
10	The divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.	No	34 does not end with 0.

Pairing the Factors of 34

Let us now pair the factors of 34. We know that the factors of 34 are 1, 2, 17 and 34. Now, let us pair these numbers. We know that 1 x 34 = 34 and 2 x 17 = 34. This means that there can be two pairs of factors of 34. These two pairs are ( 1 and 34 ) and ( 2 and 17 ). These pairs of factors of 34 can thus be represented in the below table as –

Factor of 34	Pairs of factors of 34
1, 2, 17, 34	First pair – 1 and 34 since 1 x 34 = 34
	Second Pair – 2 and 17 since 2 x 17 = 34

Now that we know the factors of 34 let us analyse what type of numbers are the factors 34

Prime Factors of 34

We know that a number having only two factors is called a prime number. The two factors are the number 1 and the number itself. For example, consider the number 7. The number 7 has only factors, 1 and the number 7 itself. Therefore, 7 is a prime number. Similarly, the number 11 is also a prime number as it has only two factors, 1 and the number 11 itself. So, does the number 34 have any prime numbers as its factor? Let us find out.

Let us list down the factors of 34. The factors are – 1, 2, 17 and 34. Let us analyse each factor one by one.

1 as a factor of 34 – We know that the number 1 is neither prime nor composite. Hence though 1 is a factor of 34, it is not a prime number. So, we can say that 1 is not a prime factor of 34.

2 as a factor of 34 – We know that 2 is the smallest prime number. This is because it has only two factors, 1 and the number 2 itself. Hence, 2 is a prime factor of 34.

17 as a factor of 34 – We know that 17 is the smallest prime number. This is because it has only two factors, 1 and the number 17 itself. Hence, 17 is a prime factor of 34.

34 as a factor of 34 – We know that 34 is a composite number. This is because we already know that there are more than 2 factors of 34, namely, 1, 2, 17 and the number 34 itself. Hence, 34 is a factor of 34 but is not a prime number.

From the above discussion, we can say that the prime factors of 34 are –

Prime Numbers as Factors of 34

2 and 17

Hence, there are 2 prime factors of 34.

Co-Prime Numbers as Factors of 34

Let us recall that co-prime numbers are the numbers that have no common factor apart from 1. Co-prime numbers are different from prime numbers. While prime numbers are all odd numbers with the only exception being 2 which is an even number, the co-prime numbers can be both prime and composite with the only condition being that they have no other factor other than 1. Let us now check whether any co-prime numbers are the factors of 34.

We now know that the numbers 1, 2, 17 and 34 are the factors of 34. Let us consider these numbers as pairs one by one.

1 and 2 – We know that 1 is neither a prime nor a composite number. 2 on the other hand is a prime number. Hence, the pair of 1 and 2 cannot be co-prime factors of 34.

1 and 17 – We know that 1 is neither a prime nor a composite number. 17 on the other hand is a prime number. Hence, the pair of 1 and 17 cannot be co-prime factors of 34.

1 and 34 – We know that 1 is neither a prime nor a composite number. 34 on the other hand is a composite number. Hence, the pair of 1 and 34 cannot be co-prime factors of 34.

2 and 17 – We know that 2 is a prime number. The other number of the pair, 17 is also a prime number. This means that the numbers 2 and 17 have no common factors other than 1. Hence, we can say that the pair of 2 and 17 is a pair of co-primes that is a factor of the number 34.

2 and 34 – We know that 2 is a prime number. 34 on the other hand is a composite number. Hence, the pair of 2 and 34 cannot be co-prime factors of 34.

17 and 34 – We know that 17 is a prime number. 34 on the other hand is a composite number. Hence, the pair of 17 and 34 cannot be co-prime factors of 34.

From the above discussion, we can say that the pair of 2 and 17 is a pair of co-primes that is a factor of the number 34.

Properties of factors of 34

There are some general properties of factors that are satisfied by the factors of any number. The following general properties of factors are satisfied by the factors of 34 –

1 is a factor of every number. Factors of 34 satisfy this property as 1 is a factor of 34.
Every number is a factor of itself. Factors of 34 satisfy this property as 34 is a factor of itself.
Every factor of a number is an exact divisor of the number itself. Factors of 34 satisfy this property as 34 is an exact divisor of itself.

Factors of a given number are finite. Factors of 34 satisfy this property as the number of factors of 34 is finite.

Common Factors of 34 with other numbers

We know that each number has its own set of factors. However, there are many numbers that have some factors in common. Those factors which are common among the factors of two or more numbers are known as common factors. Let us check whether 34 has a common factor with any other number.

We know that the factors of 34 are – 1, 2, 17 and 34

Let us consider another number say 48. What will be the factors of 48? Let us find out.

The factors of 48 will be 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48

Can we see any common factors between 34 and 48? The answer is yes. The common factors are 1 and 2.

So, 1 and 2 are two common factors between 34 and 48. Out of these 2 is the highest common factor between these two numbers. Can we assign a name to this highest common factor? Yes. Let us learn more about it.

The highest common factor ( H. C. F. ) of two or more numbers is the greatest or the largest among common factors. In other words, the H. C. F. of two or more numbers is the largest number that divides all the given numbers exactly.

Let us understand how to find HCF between 34 and other numbers.

Prime Factorisation method

In order to find the highest common factor ( H. C. F. ) of two or more numbers, the following steps are followed-

Obtain the numbers.
Write the prime factorisation of all the numbers.
Identify the common factors.
For each common prime factor find the minimum number of times it occurs in the prime factorisation of the given numbers.
Multiply each common prime factor the number of times determine the previous step and find their product to get the highest common factor ( H. C. F. ) of the given numbers.

Let us understand the above steps through an example.

Suppose we want to find the highest common factor ( H. C. F. ) of 34 and 48. We shall follow the above-listed steps for this purpose.

Obtain the numbers. We have the numbers as 34 and 48.
Write the prime factorisation of all the numbers. We have,
34 = 2 x 17 and 48 = 2 x 2 x 2 x 2 x 3
Identify the common factors. We can see from above that the common factors of 34 and 48 is 2
For each common prime factor find the minimum number of times it occurs in the prime factorisation of the given numbers. We can see that the common factor 2 appears one time in the prime factorisation of 34 while it appears 4 times in the prime factorisation of 48.
Multiply each common prime factor the number of times determine the previous step and find their product to get the highest common factor ( H. C. F. ) of the given numbers. H. C. F. of 34 and 48 = 2 x1 = 2

In this manner, we can find the highest common factor between 34 and other numbers.
