What is 26 factorial ?

To find 26 factorial, or 26!, simply use the formula that multiplies the number 26 by all positive whole numbers less than it.

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

  26! is exactly : 403291461126605635584000000

  Factorial of 26 can be calculated as:
26! = 26 x 25 x 24 x 23 x ... x 3 x 2 x 1

  The number of trailing zeros in 26! is 6

  The number of digits in 26 factorial is 27.

• 22 Factorial
• 23 Factorial
• 24 Factorial
• 25 Factorial
• Factorial of 27
• Factorial of 28
• Factorial of 29
• Factorial of 30

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

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

Symbolically, it is symbolized as "!".

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

To find the factorial of any given number, alternate the value for n in the given equation :

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

The expansion of the formula provides numbers to be replicated together 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 :
26! Factorial = 26 x 25 x 24 x 23 x ... x 3 x 2 x 1 = 26 × 25! = 403291461126605635584000000

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"
