    public void checkCoprime() {
        
        Scanner in = new Scanner(System.in);
        System.out.print("Enter a: ");
        int a = in.nextInt();
        System.out.print("Enter b: ");
        int b = in.nextInt();
        
        int hcf = 1;
        
        for (int i = 1; i <= a && i <= b; i++) {
            if (a % i == 0 && b % i == 0)
                hcf = i;
        }
        
        if (hcf == 1)
            System.out.println(a + " and " + b + " are co-prime");
        else
