What is 63 factorial ?

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.

• 59 Factorial
• 60 Factorial
• 61 Factorial
• 62 Factorial
• Factorial of 64
• Factorial of 65
• Factorial of 66
• Factorial of 67

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

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

Symbolically, it is represented as "!".

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

To find the factorial of any given number, replace the 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 prior 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 :
63! Factorial = 63 x 62 x 61 x 60 x ... x 3 x 2 x 1 = 63 × 62! = 1982608315404440064116146708361898137544773690227268628106279599612729753600000000000000

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"

1) Can we have factorials for negative numbers ?
  Negative integer factorials are undefined

2) What Is 0!
 Zero factorial or Factorial of 0 is simple, and its own value is equal to 1. So, 0! = 1.
