       Scanner sc=new Scanner(System.in);

       System.out.print("Enter a number: ");

       n=sc.nextInt();

       System.out.print("Factors of "+n+" are:");

       for(i=1;i<=n;i++)   {

           if(n%i==0)  {

               System.out.print(i);

               if(i!=n)

                   System.out.print(",");

   }

}

Explanation:

• This is a very simple program. Iterate a loop in the range 1 till n (number). Now, using % (modulus) operator, check if the number is divisible by the loop variable. If divisible, display the value of the loop variable.
