import java.util.*;
public class Factotial 
{
	public static void main(String[] args) 
	{
		Scanner s = new Scanner(System.in);
		System.out.println("\n Enter Number...");
		int number = s.nextInt();
		int fact=1;
			for(int i=1;i<=number;i++)
			{
				fact=fact*i;
			}
	System.out.println("\n Factorial of "+number+" is = "+fact);
	}
}
