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

  63! is exactly : 1982608315404440064116146708361898137544773690227268628106279599612729753600000000000000

  Factorial of 63 can be calculated as:
63! = 63 x 62 x 61 x 60 x ... x 3 x 2 x 1

  The number of trailing zeros in 63! is 15

  The number of digits in 63 factorial is 88.

What Is Factorial?

A factorial is symbolized by an integer and an exclamation symbol. In arithmetic, factorial is a multiplication process of natural numbers .

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

Symbolically, it is symbolized as "!".

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

Factorial Formula

To find the factorial of any given number, alternate 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 gives the numbers to be replicated with each other to find the factorial of the number.

We can also measure 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 :
63! Factorial = 63 x 62 x 61 x 60 x ... x 3 x 2 x 1 = 63 × 62! = 1982608315404440064116146708361898137544773690227268628106279599612729753600000000000000

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"
