Question 242034
Prime Factorization

"Prime Factorization" is finding which prime numbers you need to multiply together to get the original number. 

Use the factor tree method.

I cannot draw the factor tree here but here is what we do.

5 * 63 = 315

Break down 63 = 7 * 9

Then break down 9 into 3 * 3 or 3^2.  


Final answer: 5*7*3^2
