Java while loop find the factors of an integer

Question

We would like to write a program that reads an integer.

Display all its smallest factors in increasing order.

For example, if the input integer is 120, the output should be as follows: 2, 2, 2, 3, 5. 

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    // Create a Scanner
    Scanner input = new Scanner(System.in);

    // Prompt the user to enter an integer
    System.out.print("Enter an integer: ");
    int number = input.nextInt();
    int index = 2; // Numbers to test as factors 

    // Find and display all the smallest factors in increasing order
    //your code here
  }//www.  j av a2  s .c o  m
}




import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    // Create a Scanner
    Scanner input = new Scanner(System.in);

    // Prompt the user to enter an integer
    System.out.print("Enter an integer: ");
    int number = input.nextInt();
    int index = 2; // Numbers to test as factors 

    // Find and display all the smallest factors in increasing order
    while (number / index != 1) {
      // Test as a factor of number
      if (number % index  == 0) {
        System.out.print(index + ", ");
        number /= index; 
      }
      else
        index++; // Increment index
    }
    System.out.println(number + ".");
  }
}
