What is the prime factorization of 312?
Fofino [41]
You find the prime factorization by breaking the number down into other numbers that are prime.  Start by breaking up 312 into 39 * 8.  39 breaks up into 3 * 13, and 8 breaks up into 4 * 2 which breaks up into 2 * 2.  So the prime factorization of 312 is 3 * 13 * 2 * 2 * 2 or 3*13* 2^{3}.  When you multiply those together you'll get 312.
