What Is Factorial?
A factorial is showed by an integer and an exclamation symbol. In Mathematics, factorial is a multiplication process of natural numbers .
It multiplies the number by every noreal number that is less than it .
Symbolically, it is displayed as "!".
The function is used, among other things, to get the "n" way items can be established .
Factorial Formula
To find the factorial of any given number, change the exact value for n in the given solution :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula provides numbers to be replicated collectively to have the factorial of the number.
We can also calculate a factorial from the previous one. The factorial of any number is that number multiplied the factorial of (that number minus 1).
So the rule is : n! = n × (n−1)!
Example :
68! Factorial =
68 x 67 x 66 x 65 x ... x 3 x 2 x 1 =
68 × 67! =
