What Is Factorial?
A factorial is displayed by an integer and an exclamation mark. In arithmetic, factorial is a multiplication function of natural numbers .
It multiplies the number by every natural number that is less than it .
Symbolically, it is showed 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, exchange 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 shows the numbers to be multiplied together with each other to receive the factorial of the number.
We can also calculate a factorial from the previous 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 :
24! Factorial =
24 x 23 x 22 x 21 x ... x 3 x 2 x 1 =
24 × 23! =
