### What is factorial of 8?

Definition of factorial of 8

The factorial is a basically a quantity which is defined for integer value 8 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 8 is calculated as 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

### Factorial Formula for 8 For 8 is natural number which is greater than or equal to 1. Then we can have the formula as

8! = 8 x (8-1) X (8-2) X (8-3) X (8-4) X (8-5) X (8-6) X (8-7) X (8-8) ..... 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

### Factorial examples

Example 1:-

What is the factorial of 9?

Solution :-

We know that factorial formula for 9 is
9! = 9 × (9-1) X (9-2) X (9-3) X (9-4) X (9-5) X (9-6) X (9-7) X (9-8) X (9-9) ..... 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

So the factorial of 9 is

9! = 9 X (9-1) X (9-2) X (9-3) X (9-4) X (9-5) X (9-6) X (9-7) X (9-8) X (9-9)

9! = 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

9! = 362880

Example 2:-

What is the factorial of 10?

Solution :-

We know that factorial formula for 9 is
10! = 10 × (10-1) X (10-2) X (10-3) X (10-4) X (10-5) X (10-6) X (10-7) X (10-8) X (10-9) X (10-10) ..... 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

So the factorial of 10 is

10! = 10 X (10-1) X (10-2) X (10-3) X (10-4) X (10-5) X (10-6) X (10-7) X (10-8) X (10-9) X (10-10)

10! = 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

10! = 3628800

Example 3:-

What is the factorial of 11?

Solution :-

We know that factorial formula for 11 is
11! = 11 × (11-1) X (11-2) X (11-3) X (11-4) X (11-5) X (11-6) X (11-7) X (11-8) X (11-9) X (11-10) X (11-11) ..... 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

So the factorial of 11 is

11! = 11 X (11-1) X (11-2) X (11-3) X (11-4) X (11-5) X (11-6) X (11-7) X (11-8) X (11-9) X (11-10) X (11-11)

11! = 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

11! = 39916800
