Factorials

Enter the number in the box, then select the thousand separator (none, space, comma, decimal point or apostrophe).

The factorial of a number is the product of all of the whole numbers from 1 to the number, as per the following equation:

Then click on the button, and the factorial of the number will appear in the box, with the selected thousand-separators. Once the factorial appears in the box below, you can right click it, select the number, and then copy it to other places, like in a word processor document for example.

WARNING: This script uses Javascript, which is client-side scripting. This means that your device does the calculating and displays it in the box below. The larger the number inputted, the longer it will take to process the output. If you have an older (and less powerful) device, it is recommended that you avoid inputting larger numbers (say, trying to get the factorial of more than 2000), otherwise you run the risk of the device freezing up. I take no responsibility for device crashes (including consequent loss of unsaved data) as a result of inputting extremely large numbers where your device is perhaps not up to the task.
