What is a Factorial?

A factorial is a function that multiplies a number by every number below it. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120. The function is used, among other things, to find the number of ways “n” objects can be arranged.

Factorial Formula

n! = n × (n - 1) × (n - 2) × (n - 3) × ... × 1

For example:

Factorial of 10
10! = 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 3,628,800

By definition, the factorial of 0 is 1: 0! = 1

Factorial Examples

There are n! ways of arranging n distinct objects into an ordered sequence.

n: the set or population

In mathematics, there are n! ways to arrange n objects in sequence. "The factorial n! gives the number of ways in which n objects can be permuted."

For example:

• 2 factorial: 2! = 2 × 1 = 2
  There are 2 different ways to arrange the numbers 1 through 2: {1, 2} and {2, 1}.
• 4 factorial: 4! = 4 × 3 × 2 × 1 = 24
  There are 24 different ways to arrange the numbers 1 through 4.
• 5 factorial: 5! = 5 × 4 × 3 × 2 × 1 = 120
• 0 factorial: 0! = 1
  There is exactly 1 way to arrange 0 objects.

Description

Instead of calculating a factorial one digit at a time, use this calculator to calculate the factorial n! of a number n. This advanced factorial calculator is engineered to handle the computation of factorials for integers up to 5 digits long with efficiency and accuracy. Rather than computing the factorial incrementally one digit at a time, this tool delivers both the full long integer result and the scientific notation for exceptionally large factorials. The factorial of a number ( n ), represented as ( n! ), is the product of all positive integers from 1 to ( n ). It is a fundamental concept in mathematics, particularly useful in fields such as combinatorics, algebra, and calculus for determining permutations, combinations, and complex equations. This calculator not only streamlines the process by providing instantaneous results but also formats the outcome in scientific notation for easier handling of large numbers. For detailed examination or further computational work, you can easily copy the long integer result and paste it into other applications. This tool is ideal for students, researchers, and professionals who need to perform factorial calculations efficiently, making it a valuable resource for solving mathematical problems and analyzing statistical data..
