Write a java program to find the lcm .Given input in the form of day interval of dinner. Find the day on which they both will lunch together / dinner together.

import java.util.Scanner; public class lcm { public static void main(String[] args) { Scanner sc = new Scanner(System.in); System.out.println("Enter the day interval of Sam:"); int n1 = sc.nextInt(); System.out.println("Enter the day interval of Riya:"); int n2 = sc.nextInt(); if(n1<=0 || n2<=0) { System.out.println("Given interval is not valid"); return; } int lcm; lcm = (n1 > n2) ? n1 : n2; while(true) { if( lcm % n1 == 0 && lcm % n2 == 0 ) { System.out.printf("Sam and Riya will have their dinner on day "+lcm); break; } ++lcm; } } }
