To find 75 factorial, or 75!, simply use the formula that multiplies the number 75 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Seventy-five :

  75! is exactly : 24809140811395398091946477116594033660926243886570122837795894512655842677572867409443815424000000000000000000

  Factorial of 75 can be calculated as:
75! = 75 x 74 x 73 x 72 x ... x 3 x 2 x 1

  The number of trailing zeros in 75! is 18

  The number of digits in 75 factorial is 110.

What Is Factorial?

A factorial is symbolized by an integer and an exclamation mark. In Mathematics, factorial is a multiplication treatment of natural numbers .

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

Symbolically, it is represented as "!".

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

Factorial Formula

To find the factorial of any given number, replace the exact value for n in the given formulation :

n! = n × (n-1) × (n-2) × (n-3) × ….× 3 × 2 × 1

The expansion of the formula provides numbers to be multiplied with each other to find the factorial of the number.

We can also work out 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 :
75! Factorial = 75 x 74 x 73 x 72 x ... x 3 x 2 x 1 = 75 × 74! = 24809140811395398091946477116594033660926243886570122837795894512655842677572867409443815424000000000000000000

What are Factorials Used For?

The best use of factorial is in Combinations and Permutations.

Example : Determine how to arrange letters without repeating?

There one way for 1 letter "a":
2 ways for two letters "ab": ab, ba.
There are 6 ways for 3 letters "abc": abc acb cab bac bca.
There are 24 ways for 1234 of the letters "abcd"
