apcsaLoopsSumFactors


Given an int input, compute the sum of all the factors of the input. A factor of num is a number from 1 to num that num divides with no remainder, in other words: num % factor == 0. 


Note: When the sum of the factors is num+1, what does that mean you have found?


Note: What is the interesting pattern when num is a power of 2?

apcsaLoopsSumFactors(5) → 6
apcsaLoopsSumFactors(100) → 217
apcsaLoopsSumFactors(103) → 104
...Save, Compile, Run (ctrl-enter)
public int apcsaLoopsSumFactors(int num) {
  
}
