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 symbolized by an integer and an exclamation mark. In Mathematics, factorial is a multiplication operation 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 determined .

To find the factorial of any given number, substitute the exact value for n in the given solution :

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

The expansion of the formula provides numbers to be multiplied to 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 :
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"
