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

Here is how to get all factors of the given number.

public class Factors {

    public static void main(String[] args){
        int n = 420;

        for(int i=2; i<=n; i++){
            while(n%i==0){
                System.out.println(i + "| " + n);
                System.out.println(" -----");
                n = n/i;
            }
        }
    }
}

Output:

2| 420
 -----
2| 210
 -----
3| 105
 -----
5| 35
 -----
7| 7
