Hello Friend,

Try the following code:

import java.util.*;
class  RelativelyPrime
{
    public static int check(int a, int b) {
                if (b == 0)
                        return a;
                else
                        return check(b, a % b);
        }

    public static void main(String[] args) 
    {
        RelativelyPrime rel=new RelativelyPrime();
        Scanner input=new Scanner(System.in);
        System.out.print("Enter first number: ");
        int num1=input.nextInt();
        System.out.print("Enter second number: ");
        int num2=input.nextInt();
        int res=rel.check(num1,num2);
        if(res==1){
         System.out.println("Numbers are relatively prime");
        }
        else{
         System.out.println("Numbers are not relatively prime");
        }

    }
}

Thanks
