Factorial Calculator

The nth factorial is the product of all the numbers from 1 up to n. Also, factorials use the "!" notation, so n! is the nth factorial. The 4th factorial would be 24 because 1 × 2 × 3 × 4 = 24. Factorials are useful for calculating how many permutations that can be made up using a set of given objects. For example: If you have 4 different coloured boxes next to each other in a line, you could rearrange them in 24 different orders.

Please Note: Browsers may have difficulty trying to display larger factorials and may possibly crash. Certain browsers may not allow you to copy very easily, so please feel free to download larger results as a text file.

Input Limit: There is an input limit between 1 and 100,000.

Input of n!: (required)

Information

I will soon be making a feature that will allow even higher factorials to be produced (as high as 10 million!) so please hold tight!

I've produced 5,664 factorials to the public. That's a grand total of 358,277,170 digits in length produced!
