Product of all the factors To find product of all the factors we follow the following steps: Step1: Prime factorisation N ... A number that has only two factors, 1 and the number itself, is called a prime number. Any prime number will have only a single factor pair. Example: for the prime number 17: 17 × 1 = 17, therefore it has only one factor pair. You most often want to find the "prime factorization" of a number: the list of all the prime-number factors of a given number. The prime factorization does not include 1, but does include every copy of every prime factor. For instance, the prime factorization of 8 is 2×2×2, not just "2".
