Let's look at how to calculate the Factorial of Ninety-three :

  93! is exactly : 1156772507081641574759205162306240436214753229576413535186142281213246807121467315215203289516844845303838996289387078090752000000000000000000000

  Factorial of 93 can be calculated as:
93! = 93 x 92 x 91 x 90 x ... x 3 x 2 x 1

  The number of trailing zeros in 93! is 22

  The number of digits in 93 factorial is 145.

What Is Factorial?

A factorial is represented by an integer and an exclamation tag. In Mathematics, factorial is a multiplication function of natural numbers .

It multiplies the number by every natural number that is less than it .

Symbolically, it is displayed as "!".

The function is used, among other things, to get the "n" way pieces can be determined .

Factorial Formula

To find the factorial of any given number, change the exact value for n in the given formula :

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 have the factorial of the number.

We can also measure 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 :
93! Factorial = 93 x 92 x 91 x 90 x ... x 3 x 2 x 1 = 93 × 92! = 1156772507081641574759205162306240436214753229576413535186142281213246807121467315215203289516844845303838996289387078090752000000000000000000000

What are Factorials Used For?
