How to take LCM of two nos in java (Jayanthi ganesh)

import java.util.*;

public class LCM {
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
int i;
int n1=sc.nextInt();
int n2=sc.nextInt();
int GCD=1;
int LCM=1;
for(i=1; i<1000; i++)
if((n1%i==0) && (n2%i==0))
{
GCD=i;
}
LCM=(n1*n2)/GCD;
System.out.println("LCM=" + LCM);
}
}
