What Is Factorial?
A factorial is represented by an integer and an exclamation symbol. In arithmetic, factorial is a multiplication treatment of natural numbers .
It multiplies the number by every basic number that is less than it .
Symbolically, it is displayed as "!".
The function is used, among other things, to find the "n" way objects can be positioned .
To find the factorial of any given number, change the exact value for n in the given way :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula provides numbers to be multiplied at the same time to have the factorial of the number.
We can also work out a factorial from the prior one. The factorial of any number is that number times the factorial of (that number minus 1).
So the rule is : n! = n × (n−1)!
22! Factorial = 22 x 21 x 20 x 19 x ... x 3 x 2 x 1 = 22 × 21! = 1124000727777607680000
