What is 67 factorial ?

To find 67 factorial, or 67!, simply use the formula that multiplies the number 67 by all positive whole numbers less than it.

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

  67! is exactly : 36471110918188685288249859096605464427167635314049524593701628500267962436943872000000000000000

  Factorial of 67 can be calculated as:
67! = 67 x 66 x 65 x 64 x ... x 3 x 2 x 1

  The number of trailing zeros in 67! is 16

  The number of digits in 67 factorial is 95.

• 63 Factorial
• 64 Factorial
• 65 Factorial
• 66 Factorial
• Factorial of 68
• Factorial of 69
• Factorial of 70
• Factorial of 71

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

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

Symbolically, it is symbolized as "!".

The function is used, among other things, to find the "n" way items 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 the numbers to be multiplied at the same time to get the factorial of the number.

We can also calculate a factorial from the previous 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 :
67! Factorial = 67 x 66 x 65 x 64 x ... x 3 x 2 x 1 = 67 × 66! = 36471110918188685288249859096605464427167635314049524593701628500267962436943872000000000000000

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"
