What Is Factorial?
A factorial is displayed by an integer and an exclamation mark. In Mathematics, factorial is a multiplication procedure of natural numbers .
It multiplies the number by every natural number that is less than it .
Symbolically, it is listed as "!".
The function is used, among other things, to get the "n" way things can be determined .
Factorial Formula
To find the factorial of any given number, replace the exact value for n in the given rule :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula shows the numbers to be multiplied to each other to find the factorial of the number.
We can also calculate 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 :
83! Factorial =
83 x 82 x 81 x 80 x ... x 3 x 2 x 1 =
83 × 82! =
