Java program to input two integers and find their Least Common Multiple

Write a program to input two integers and find their Least Common Multiple(L.C.M).

For Example,

INPUT: Enter 2 integers:

12

8

OUTPUT: L.C.M. = 24

import java.util.*;
class LCM
{
	public static void main(String arr[])
	{
		Scanner sc=new Scanner(System.in);
		int i,a,b,l=0;
		System.out.println("Enter 2 integer:");
		a=sc.nextInt();
		b=sc.nextInt();
		for(i=a;i<=a*b;i++)
		{
			if(i%a==0 && i%b==0)
			{
				l=i;
				break;
			}
		}
		System.out.println("L.C.M.="+l);
	}
}
