What Is Factorial?
A factorial is represented by an integer and an exclamation mark. In math concepts, factorial is a multiplication operation of natural numbers .
It multiplies the number by every noreal number that is less than it .
Symbolically, it is showed as "!".
The function is used, among other things, to find the "n" way objects can be structured .
Factorial Formula
To find the factorial of any given number, exchange the value for n in the given formulation :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula provides the numbers to be replicated with each other to get the factorial of the number.
We can also determine a factorial from the previous one. The factorial of any number is that number replicated the factorial of (that number minus 1).
So the rule is : n! = n × (n−1)!
Example :
97! Factorial =
97 x 96 x 95 x 94 x ... x 3 x 2 x 1 =
97 × 96! =
