Best Answer

Prime factors are prime numbers that are factors of a given number. Example: All factors of 420 are 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, and 420, but the prime factors having a product of 420 when multiplied together are 2 x 2 x 3 x 5 x 7.
All nonzero numbers have factors. Some factors are prime numbers. These are known as prime factors. 1, 2, 3 and 6 are the factors of 6. 2 and 3 are the prime factors of 6.

Prime factorization is finding the factors of a number that are all prime. Here's how you do it: Find 2 factors of your number. Then look at your 2 factors and determine if one or both of them is not prime. If it is not a prime factor it. Repeat this process until all your factors are prime. Here's an example:

Find the prime factors of the number 84: 84 / \ 42 x 2 (84 is 42 times 2) / \ 21 x 2 (42 is 21 times 2) / \ 7 x 3 (21 is 7 times 3) (7 and 3 are both prime, so we stop!)

So the prime factors of 84 are 7 x 3 x 2 x 2.
