Instead of calculating a factorial one digit at a time, use this calculator to calculate the factorial n! of a number n. Enter an integer, up to 5 digits long. You will get the long integer answer and also the scientific notation for large factorials.
Example: 4! is shorthand for 4 × 3 × 2 × 1. The factorial function (symbol: !) says to multiply all whole numbers from our chosen number down to 1. We can easily calculate a factorial from the previous one: As a table: n! = 2 × 1! = 3 × 2! = 4 × 3! = 5 × 4! Example: 9! equals 362,880. Try to calculate 10! 10! = 10 × 9!
The factorial of a whole number n, denoted as n!, is the product of all the whole numbers between 1 and n: 1×2×3×…×(n−1)×n. So 3! would be 1×2×3 = 6.
You can use our Factorial Calculator to calculate the factorial of any real number between 0 and 5,000. To use this calculator just enter a positive integer number less than or equal to 5000. After you click "Calculate Factorial" the result will be displayed in the output box.
In mathematics, the factorial of a non-negative integer , denoted by , is the product of all positive integers less than or equal to . The factorial of also equals the product of with the next smaller factorial: For example, The value of 0! is 1, according to the convention for an empty product. [1]

This factorial calculator helps you calculate any factorial operation which is a function that makes the product of all positive integers less than or equal to a given number.
Definition of a Factorial. The factorial of a number is the multiplication of all the numbers between 1 and the number itself. It is written like this: n!. So the factorial of 2 is 2! (= 1 × 2). To calculate a factorial you need to know two things: 0! = 1; n! = (n - 1)! × n

In mathematics, the double factorial of a number n, denoted by n‼, is the product of all the positive integers up to n that have the same parity (odd or even) as n. [1] . That is, ⌈ ⌉ {\displaystyle n!!=\prod _ {k=0}^ {\left\lceil {\frac {n} {2}}\right\rceil -1} (n-2k)=n (n-2) (n-4)\cdots .}
