What is 22 factorial ?

To find 22 factorial, or 22!, simply use the formula that multiplies the number 22 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Twenty-two :

  22! is exactly : 1124000727777607680000

  Factorial of 22 can be calculated as:
22! = 22 x 21 x 20 x 19 x ... x 3 x 2 x 1

  The number of trailing zeros in 22! is 4

  The number of digits in 22 factorial is 22.

• 18 Factorial
• 19 Factorial
• 20 Factorial
• 21 Factorial
• Factorial of 23
• Factorial of 24
• Factorial of 25
• Factorial of 26

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

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

Symbolically, it is displayed as "!".

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

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 provides numbers to be multiplied at the same time to have 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 :
22! Factorial = 22 x 21 x 20 x 19 x ... x 3 x 2 x 1 = 22 × 21! = 1124000727777607680000

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"
