        """
        uglyFactors = [2,3,5]
        if num == 0: return False
        if num == 1: return True
        
        while True:
            if num in uglyFactors:
                return True
            
            factorFound = False
            for factor in uglyFactors:
                if num % factor == 0:
                    factorFound = True
                    num /= factor
                    break
            
            if not factorFound:
                return False

Problem solution in Java.

class Solution {
    public boolean isUgly(int num) {
        int n =num;
        
        while(n>0){
            while(n%2 == 0){
                n= n/2;
            }
            while(n%3 ==0){
                n=n/3;
