Hints
Use the class BigInteger from the built-in .NET library System.Numerics.dll.
1.  Import the namespace “System.Numerics”:

2.  Use the type BigInteger to calculate the number factorial.

3.  Loop from 2 to N and multiply every number with factorial.

using System;
using System.Numerics;

namespace _03.BigFactorial
{
    class Program
    {
        static void Main(string[] args)
        {
            var number = int.Parse(Console.ReadLine());

            BigInteger bigInteger = 1;
            for (int i = number; i > 0; i--)
            {
                bigInteger *= i;
            }
            Console.WriteLine(bigInteger);
        }
    }
