Question

Please write answer in java:

Our goal is to write a function (not a snippet—no more snippets from this point forward) called lcm that computes the least common multiple of two integers. While there are clever algorithms for solving this problem, we encourage you to try something simple.

Answer 1

//LCM.java
import java.util.Scanner;
public class LCM {
    public static int getLCM(int a, int b){
        int min = a;
        if(min > b){
            min = b;
        }
        while(!((min%a==0) && (min%b==0))){
            min++;
        }
        return min;
    }

    public static void main(String args[]) {
        int num1, num2;
        Scanner in = new Scanner(System.in);
        System.out.print("Enter number1: ");
        num1 = in.nextInt();
        System.out.print("Enter number2: ");
        num2 = in.nextInt();
        System.out.println("LCM = "+getLCM(num1,num2));
    }
}

Enter number1: 15 Enter number2: 30 LCM = 30
