using System;

public class Program

{

 public static void Main()

 {

 Program pr = new Program();

    long fact = pr.factorial(10);

    Console.WriteLine('factorial of {0} is : {1}',10,fact);

 }

 public long factorial(long n) {

        if (n == 1)

      return 1;

     else

      return (n * factorial(n - 1));

    }

}

Output.
