Factorial Calculator

What is a Factorial?

A factorial is a mathematical operation represented by an exclamation mark (!). It means you must multiply a number by all its positive integer predecessors. For example, to calculate the factorial of 4 (4!), the calculation would be 4 x 3 x 2 x 1 = 24. Factorials are widely used in areas such as probability and combinatorics, to find the number of possible combinations or arrangements.
