The factorials

Rule

Each term is: The factorial of the number

Known as: The factorials

The product of each integer between 1 and the number.

The first 19 terms (starting from n=1) are:

1 2 6 24 120 720 5040 40320 362880 3628800 39916800 479001600 6227020800 87178291200 1307674368000 20922789888000 355687428096000 6402373705728000 121645100408832000

Example

To get the value for n=11:

• Find 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1, giving 39916800.

So the result is 39916800.
