            {
                Console.WriteLine("The factorial of 4 is: {0}\n",
                    Factorial(4));
            }
            catch(Exception ex)
            {
                //handle exception here
            }
            Console.ReadLine();           
        }

        static long Factorial(long number)
        {
            long FinalNumber = 1;
            for (int i = 1; i <= number; i++)
            {
                FinalNumber = FinalNumber * i;
            }
            return FinalNumber;
        }
    }
