public class GCDFinder {

    public static int gcd(int a,int b){
        int temp = a % b;
        if(temp == 0)
            return b;
        else
            return gcd(b,temp);
        }

    public static void main(String args[]){
        System.out.println("GCD of 12 and 10 is : " + gcd(12,10));
    }
}

Output :

GCD of 12 and 10 is : 2

Note : You can calculate LCM as Number1*Number2/GCD
