## How Factorial is Calculated?

Factorial is simply defined as “the product of an integer (n) and all the integers below it. For Example- Factorial three ( 3*!* ) is equal to 6

Factorial of a number ‘N’ is represented as N!

N! is calculated as N*(N-1)*(N-2)*(N-3)……*1

Let the Value of N is 5 then Factorial of N is 5*4*3*2*1=120

## C Program for Factorial of a Number:

**#include <stdio.h>**

** #include <conio.h>**

** int main()**

** {**

** int n, i;**

** unsigned long long fact = 1;**

** clrscr();**

** printf(“Enter a number to Find its Factorial: “);**

** scanf(“%d”,&n);**

** if (n < 0)**

** printf(“Error! Factorial of a negative number doesn’t exist”);**

** else**

** {**

** for(i=1; i<=n; i++)**

** {**

** fact = fact * i;**

** }**

** printf(“Factorial of %d = %llu”, n, fact);**

** }**

** getch();**

** return 0;**

** }**

## Output:

Enter a number to Find its Factorial: 6

Factorial of 6 = 720
