What is factorial of 12?

Definition of factorial of 12

The factorial is a basically a quantity which is defined for integer value 12 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 12 is calculated as 12 X 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

Factorial Formula for 12

For 12 is natural number which is greater than or equal to 1. Then we can have the formula as

12! = 12 x (12-1) X (12-2) X (12-3) X (12-4) X (12-5) X (12-6) X (12-7) X (12-8) X (12-9) X (12-10) X (12-11) X (12-12) ..... 12 X 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

Factorial examples

Example 1:-

What is the factorial of 13?

Solution :-

We know that factorial formula for 13 is
13! = 13 × (13-1) X (13-2) X (13-3) X (13-4) X (13-5) X (13-6) X (13-7) X (13-8) X (13-9) X (13-10) X (13-11) X (13-12) X (13-13) ..... 13 X 12 X 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 13 is

13! = 13 X (13-1) X (13-2) X (13-3) X (13-4) X (13-5) X (13-6) X (13-7) X (13-8) X (13-9) X (13-10) X (13-11) X (13-12) X (13-13)

13! = 13 X 12 X 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

13! = 6227020800

Example 2:-

What is the factorial of 14?

Solution :-

We know that factorial formula for 13 is
14! = 14 × (14-1) X (14-2) X (14-3) X (14-4) X (14-5) X (14-6) X (14-7) X (14-8) X (14-9) X (14-10) X (14-11) X (14-12) X (14-13) X (14-14) ..... 14 X 13 X 12 X 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 14 is

14! = 14 X (14-1) X (14-2) X (14-3) X (14-4) X (14-5) X (14-6) X (14-7) X (14-8) X (14-9) X (14-10) X (14-11) X (14-12) X (14-13) X (14-14)

14! = 14 X 13 X 12 X 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

14! = 87178291200

Example 3:-

What is the factorial of 15?

Solution :-

We know that factorial formula for 15 is
15! = 15 × (15-1) X (15-2) X (15-3) X (15-4) X (15-5) X (15-6) X (15-7) X (15-8) X (15-9) X (15-10) X (15-11) X (15-12) X (15-13) X (15-14) X (15-15) ..... 15 X 14 X 13 X 12 X 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 15 is

15! = 15 X (15-1) X (15-2) X (15-3) X (15-4) X (15-5) X (15-6) X (15-7) X (15-8) X (15-9) X (15-10) X (15-11) X (15-12) X (15-13) X (15-14) X (15-15)

15! = 15 X 14 X 13 X 12 X 11 X 10 X 9 X 8 X 7 X 6 X 5 X 4 X 3 X 2 X 1

15! = 1307674368000
