Prime Factoring ... Numbers that can be multiplied together to get another number are its factors. For example, 4*3 = 12, so 3 and 4 are factors of 12. However, they're not its only factors; 1, 2, 6, and 12 are other factors of 12. (Another way of defining a factor is a number that goes evenly into the number you...

On the other hand, the prime factorization includes ONLY the prime factors, not any products of those factors. For instance, even though 2×2 = 4, and even though 4 is a divisor of 8, 4 is NOT in the PRIME factorization of 8. That is because 8 does NOT equal 2×2×2×4!
