Finding factors of a given integer

Question

I have something like this down:

int f = 120;
for(int ff = 1; ff <= f; ff++){
    while (f % ff != 0){            
}

Is there anything w

Answer 1

I got all the factors just fine with this (I just modified the algorithm in the question).

int num1 = 120;

for(int num2=1;num2<=num1;num2++)
{
  if (num1%num2 != 0)
    System.out.println(num2);
}

Answer 2

Slightly modified solution: You can first check if variable x is divisible by variable y. If yes, we will count 1 and will repeat this process. For the loop counter, x/y is used and you should check x>0 to avoid repetition when x becomes zero but loop is not finished yet.

   public class Factor {

    public static void main(String[] args) {

        int x = 48;
        int x1 = x;
        int y = 2;
        int k = x / y;
        int j = 0;
        for (int i = 1; i < k; i++) {
            if ((x % y) == 0 && x > 0)
                j++;
            x = x / 2;
        }
        System.out.println(+x1 + " is a factor of " + y + " for " + j
                + " times.");

    }
}
