Write a Java Program to Find GCD(HCF) and LCM of Two Numbers

SOURCE CODE ::

import java.util.Scanner;

public class hcf_lcm
{
    public static void main(String args[])
    {
        int a, b, x, y, t, hcf, lcm;
        Scanner scan = new Scanner(System.in);
                
        System.out.print("Enter Two Number : ");
        x = scan.nextInt();
        y = scan.nextInt();
                
        a = x;
        b = y;
                
        while(b != 0)
        {
            t = b;
            b = a%b;
            a = t;
        }
                
        hcf = a;
        lcm = (x*y)/hcf;
                
        System.out.print("HCF = " +hcf);
        System.out.print("\nLCM = " +lcm);
    }
}

OUTPUT ::

Enter Two Number : 4
14
HCF = 2
LCM = 28
