The factorial of n, or n! is the product of all positive integer numbers from 1 to n. The value n! is called "n factorial" and is calculated by following formula: n! = n × (n - 1) × (n - 2) × . . . × 1 , n > 0. By convention, 0! = 1. For example, the factorial of 7 is equal to 7×6×5×4×3×2×1 = 5040.
The factorial function (symbol: !) says to multiply all whole numbers from our chosen number down to 1. Examples: 4! = 4 × 3 × 2 × 1 = 24. 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040. 1! = 1. We usually say (for example) 4! as "4 factorial", but some people say "4 shriek" or "4 bang".
7 Οκτ 2023 · 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.
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.
Calculating Factorials. Calculating factorials is straightforward. You simply multiply the number by every positive integer less than it until you reach 1. For instance, to calculate the factorial of 6, you would calculate 6 × 5 × 4 × 3 × 2 × 1 = 720. Example 1: Factorial of 4. Let's take the factorial of 4.
An online factorial calculator helps you to calculate the factorial of a given number (positive integer) n and shows you the step-by-step calculations.
