Oct 7, 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.
Use this factorial calculator to calculate the factorial of any real number between 0 and 5,000.
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".
The formula to calculate a factorial for a number is: n! = n × (n-1) × (n-2) × … × 1. Thus, the factorial n! is equal to n times n minus 1, times n minus 2, continuing until the number 1 is reached. We can also express the factorial formula a little differently. n! = 1 × 2 × 3 × … × n.
An online factorial calculator helps to calculate factorial (n!) of a given n positive number. Also, you can be able to add, subtract, multiply, and divide factorial of two numbers by using the factorial finder calculator.
Factorial Calculator helps to calculate the factorial of n number. The advanced factorial calculator can add, subtract, divide & multiply factorials (n1).
What is factorial? A factorial is a number defined as follows for a positive integer n n. n!=n\left (n-1\right)\left (n-2\right)\cdots3\cdot2\cdot1 n! = n(n−1)(n−2)⋯3⋅2⋅ 1. For example, the factorial of 5 can be calculated as follows. 5!=5\cdot4\cdot3\cdot2\cdot1=120 5! = 5⋅ 4⋅ 3⋅ 2⋅ 1 = 120. It is common to define the factorial of 0 as 1.
