Composite number 720 prime factorization (decomposing, breaking down into prime factors), written as a product of primes (with exponents, powers) Show
The natural numbers that are only divisible by 1 and themselves are called prime numbers.A composite number is a natural number that has at least one other factor than 1 and itself.The prime factorization of a number: finding the prime numbers that multiply together to make that number.720 is not a prime number but a composite one. 720 can be written as a product of prime numbers.The prime factorization of the composite number 720: 720 = 2 × 2 × 2 × 2 × 3 × 3 × 5The prime factorization, written in a condensed way, as a product of prime factors, with exponents (powers): *720 = 24 × 32 × 5* A number written with exponents is a base raised to the exponent (we say: the base raised to the power of the exponent). The exponent indicates how many times the base is multiplied by itself: 53 = 5 × 5 × 5 = 125. We say 5 raised to the power of 3. 53 is the power, 5 is the base, 3 is the exponent and 125 is the value of the power.The prime numbers are the building blocks of all the numbers except for 0 and 1.The composite numbers consist of prime numbers that are multiplied together.There is only one prime number that is an even number: 2. All the other prime numbers are odd numbers.The prime numbers up to 1,000The prime numbers up to 10,000The prime factorization of a number, how is it doneLet's learn by having an example: - Take the number 220 and build its prime factorizationWe need the list of the first prime numbers, ordered from 2 up to, let's say, 20: |
