            int n1, n2, i, hcf = 0;

            Console.Write("Enter first number : ");
            n1 = Convert.ToInt32(Console.ReadLine());

            Console.Write("Enter second number : ");
            n2 = Convert.ToInt32(Console.ReadLine());

            for (i = 1; i <= n1 || i <= n2; i++)
            {
                if (n1 % i == 0 && n2 % i == 0)
                hcf = i;
            }

            Console.WriteLine("HCF of {0} and {1} is {2}", n1, n2, hcf);
            Console.ReadLine();
        }
