LCM of two numbers in java

Java code to find the LCM i.e. least common factors of given two numbers

import java.io.*;

class Test {

     public static void main(String[] args) throws IOException {

          int n1,n2,x,y;

          System.out.println("Enter first number:");

          BufferedReader br1=new BufferedReader(new InputStreamReader (System.in));

          n1=Integer.parseInt(br1.readLine());

          System.out.println("Enter second number:");

          BufferedReader br2=new BufferedReader(new InputStreamReader (System.in));

          n2=Integer.parseInt(br2.readLine());

          x=n1;

          y=n2;

          while(n1!=n2){

              if(n1>n2)

                   n1=n1-n2;

              else

                   n2=n2-n1;

          }

          System.out.println("L.C.M of two number is"+x*y/n1);

     }

}
