What’s a Factorial Calculator?
This tool computes the factorial of a non-negative integer (n!), the product of all positive integers up to n. Ideal for students and educators in India and globally.
How Factorials Are Calculated
Method used:
Factorial (n!):
n! = n × (n-1) × (n-2) × ... × 1 (e.g., 5! = 5 × 4 × 3 × 2 × 1 = 120)
Special Cases:
0! = 1 by definition
Large n may produce very large results
Our calculator ensures accurate results with clear steps!

Key Considerations for Factorials
Ensure accurate results:
Uses iterative multiplication for accuracy. Large factorials may exceed display limits.
Only non-negative integers up to 100 are supported to avoid overflow.
0! = 1 by mathematical definition, used in combinatorics.
