Prime Factors of a given number

Write a program to find all prime factors of a given number.

The program should print the factors of a number which are prime.

One way of writing this is

If the number is divisible by 2, repeatedly divide the number by 2 until it is no longer divisible by 2.
Print 2 as a factor if number is divisible.
In a loop for values of i from 3 to n in steps of 2, find if a number is divisible by i.
If yes repeatedly divide by i as long as number is divisible.

here is the code for it

    void printFactors(int num){
          if(num%2==0){
            System.out.println("2 ");
            while (num%2==0)
             num = num/2;
          }
        
          for(int i=3;i<=num;i+=2){
               if(num%i==0){
                    System.out.println(i);
                  while(num%i==0)
                     num = num/i;
               }
          }

     }
