Program to find prime factors of a number in Java code example

Example 1: prime factorization java

import java.util.Scanner;

public class PrimeFactors {
   public static void main(String args[]){
      int number;
      Scanner sc = new Scanner(System.in);
      System.out.println("Enter a number ::");
      number = sc.nextInt();
      
      for(int i = 2; i< number; i++) {
         while(number%i == 0) {
            System.out.println(i+" ");
            number = number/i;
         }
      }
      if(number >2) {
         System.out.println(number);
      }
   }
}

Example 2: how to write a programme to display all the factors of a number in java

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 + " ");
            }
        }
    }
}
