Factorial Calculator
Math got you scratching your head? Whether you're tackling a homework problem, crunching numbers for a project, or just curious about how big factorials can get, this tool is here to save the day. Simply punch in a number, and voilà—your factorial result is ready in seconds. No more manual calculations or second-guessing. It's like having a math wizard in your pocket, ready to simplify your life one number at a time!
Enter a number to calculate its factorial.
How does it work? It's simpler than you think! A factorial is just the product of all positive integers up to that number. For example, the factorial of 5 (written as 5!) is calculated as 5 × 4 × 3 × 2 × 1, which equals 120. Our tool does all the heavy lifting for you—just enter a number and let it handle the rest.
