What does Factorial do that other Calculate pages on this site do not?

Exact factorial via BigInt. Shows digit length and trailing zero count. Cap 200. Short version: n! for 0–200 with digits and trailing zeros.

Does Factorial upload my file or text to Tool-You servers?

No. Factorial runs in this browser tab. Files stay on the device. Limit note: n from 0 to 200. Exact BigInt. Trailing zeros counted in decimal.

Should I use GCD and LCM instead of Factorial?

Use Factorial when you need n! for 0–200 with digits and trailing zeros. Use GCD and LCM when you need GCD and LCM of two positives; coprime flag. They share a category (Calculate) but not the same job.

What are the limits of Factorial?

n from 0 to 200. Exact BigInt. Trailing zeros counted in decimal. Also: Exact factorial via BigInt. Shows digit length and trailing zero count. Cap 200.
