What Is Factorial?
A factorial is showed by an integer and an exclamation symbol. In arithmetic, factorial is a multiplication treatment 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 structured .
Factorial Formula
To find the factorial of any given number, alternate the value for n in the given rule :
n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1
The expansion of the formula gives the numbers to be replicated with each other to receive 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)!
Example :
67! Factorial =
67 x 66 x 65 x 64 x ... x 3 x 2 x 1 =
67 × 66! =
