What is 68 factorial ?

To find 68 factorial, or 68!, simply use the formula that multiplies the number 68 by all positive whole numbers less than it.

Let's look at how to calculate the Factorial of Sixty-eight :

  68! is exactly : 2480035542436830599600990418569171581047399201355367672371710738018221445712183296000000000000000

  Factorial of 68 can be calculated as:
68! = 68 x 67 x 66 x 65 x ... x 3 x 2 x 1

  The number of trailing zeros in 68! is 16

  The number of digits in 68 factorial is 97.

• 64 Factorial
• 65 Factorial
• 66 Factorial
• 67 Factorial
• Factorial of 69
• Factorial of 70
• Factorial of 71
• Factorial of 72

A factorial is showed by an integer and an exclamation symbol. In Mathematics, factorial is a multiplication process of natural numbers .

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

Symbolically, it is displayed as "!".

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

To find the factorial of any given number, change 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 replicated collectively to have 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 :
68! Factorial = 68 x 67 x 66 x 65 x ... x 3 x 2 x 1 = 68 × 67! = 2480035542436830599600990418569171581047399201355367672371710738018221445712183296000000000000000

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"
