The factors of 12 are 1, 2, 3, 4, 6, and 12, because each of those divides 12 without leaving a remainder or, alternatively, each of those is a counting number that can be multiplied by another counting number to make A prime factor of a number is just a factor of that number that is also prime.

So, 12 has six factors — 1, 2, 3, 4, 6, and 12 — but only two of them 2 and 3 are prime, so it has only two prime factors. The prime factorization of a number is a factorization — a way of expressing that number as a product — consisting only of primes. The number 1 is not prime. See prime to learn why. Though many numbers can be factored in more than one way, their prime factorization is unique! Apart from order, there is only one way to factor any number into primes!
