Definition of factorial of 4
The factorial is a basically a quantity which is defined for integer value 4 which is greater than or equal to 0.
The factorial is nothing but the product of all intergers which is less than or equal to n but it is greater than or equal to 1. By definition we can say that the factorial value of 0 is equal to 1. We can not have negative integers factorial as defined. We can see that factorial is the result of multiplying a sequence of descending natural numbers. We can say that factorial of 4 is calculated as 4 X 3 X 2 X 1

Factorial examples
Example 1:-
What is the factorial of 5?Solution :-
We know that factorial formula for 5 is5! = 5 × (5-1) X (5-2) X (5-3) X (5-4) X (5-5) ..... 5 X 4 X 3 X 2 X 1
So the factorial of 5 is
5! = 5 X (5-1) X (5-2) X (5-3) X (5-4) X (5-5)
5! = 5 X 4 X 3 X 2 X 1
5! = 120
Example 2:-
What is the factorial of 6?Solution :-
We know that factorial formula for 5 is6! = 6 × (6-1) X (6-2) X (6-3) X (6-4) X (6-5) X (6-6) ..... 6 X 5 X 4 X 3 X 2 X 1
So the factorial of 6 is
6! = 6 X (6-1) X (6-2) X (6-3) X (6-4) X (6-5) X (6-6)
6! = 6 X 5 X 4 X 3 X 2 X 1
6! = 720
Example 3:-
What is the factorial of 7?Solution :-
We know that factorial formula for 7 is7! = 7 × (7-1) X (7-2) X (7-3) X (7-4) X (7-5) X (7-6) X (7-7) ..... 7 X 6 X 5 X 4 X 3 X 2 X 1
So the factorial of 7 is
7! = 7 X (7-1) X (7-2) X (7-3) X (7-4) X (7-5) X (7-6) X (7-7)
7! = 7 X 6 X 5 X 4 X 3 X 2 X 1
7! = 5040
