This program, like exponentiation, is another follow-on from the one that can multiply large numbers together. Here, you can calculate the factorial of a number. This is the product of all the numbers from 1 up to and including the number.
A factorial is denoted by adding an exclamation mark after the number.
One practical application of a factorial is in counting the number of possible distinct sequences – or permutations, of a number of distinct objects. For example, if you have a nuber of distinct objects in a row, in how many ways can these objects be arranged.
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.
