This will return how many factors a number has. A factor is a number that goes in to another with no remainder (Think %). So 12 has 1,2,3,4,6,12 or 6 factors. 9 has 1,3,9 or 3 factors.

numFactors(12) → 6
numFactors(9) → 3
numFactors(5) → 2

...Save, Compile, Run (ctrl-enter)

public int numFactors(int x){ }
