Java Program to Display Factors of a Number

In this program, you'll learn to display all factors of a given number using for loop in Java.

Example: Factors of a Positive Integer

public class Factors {

    public static void main(String[] args) {

        int number = 60;

        System.out.print("Factors of " + number + " are: ");
        for(int i = 1; i <= number; ++i) {
            if (number % i == 0) {
                System.out.print(i + " ");
            }
        }
    }
}

When you run the program, the output will be:

Factors of 60 are: 1 2 3 4 5 6 10 12 15 20 30 60

In the above program, number whose factors are to be found is stored in the variable number (60).

The for loop is iterated until i <= number is false. In each iteration, whether number is exactly divisible by i is checked (condition for i to be the factor of number) and the value of i is incremented by 1.
