Triple Factorial Calculator

Triple Factorial Calculator calculates the triple factorial of a given number.

What is triple factorial?
The triple factorial is similar to the factorial, but instead of decreasing by 1 at each step, it decreases by 3.
This means you multiply the number n by n-3, n-6, n-9 , and so on, until you reach a number greater than or equal to 1.

Triple Factorial Formula

The triple factorial formula is:

n!!!=n x (n-3) x (n-6) x (n-9) x (n-12)...

Example

   •Standard factorial of 12:
    12!=12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 479,001,600

   •Double factorial of 12:
    12!! = 12 x 10 x 8 x 6 x 4 x 2 = 46,080

   •Triple factorial of 12:
    12!!! = 12 x 9 x 6 x 3 x 1 = 1,944
