What is 51 factorial ?

To find 51 factorial, or 51!, simply use the formula that multiplies the number 51 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Fifty-one :

  51! is exactly : 1551118753287382280224243016469303211063259720016986112000000000000

  Factorial of 51 can be calculated as:
51! = 51 x 50 x 49 x 48 x ... x 3 x 2 x 1

  The number of trailing zeros in 51! is 12

  The number of digits in 51 factorial is 67.

• 47 Factorial
• 48 Factorial
• 49 Factorial
• 50 Factorial
• Factorial of 52
• Factorial of 53
• Factorial of 54
• Factorial of 55

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 noreal number that is less than it .

Symbolically, it is listed as "!".

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

To find the factorial of any given number, alternate the 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 multiplied together with each other to obtain the factorial of the number.

We can also calculate a factorial from the previous one. The factorial of any number is that number multiplied the factorial of (that number minus 1).

So the rule is : n! = n × (n−1)!

Example :
51! Factorial = 51 x 50 x 49 x 48 x ... x 3 x 2 x 1 = 51 × 50! = 1551118753287382280224243016469303211063259720016986112000000000000

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"
