To find 63 factorial, or 63!, simply use the formula that multiplies the number 63 by all positive whole numbers less than it.

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 displayed by an integer and an exclamation mark. In math concepts, factorial is a multiplication treatment of natural numbers .

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

Symbolically, it is listed as "!".

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

Factorial Formula

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

We can also calculate 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"
