If the number is itself prime, a notice tells you so.

FAQ

자주 묻는 질문

Q1. Can I factorize negative numbers or decimals?

No. Prime factorization is only meaningful for natural numbers 2 or greater, so negative numbers or decimals can't be calculated.

Q2. Why can't 1 be factorized?

1 is neither prime nor composite, so it isn't a valid target for factorization — only integers of 2 or greater are accepted.

Q3. Can it handle very large numbers?

It can factorize numbers under 1 trillion (1,000,000,000,000). Beyond that, the calculation could take a long time in the browser, so there's a limit.

Q4. What does a result like 2³ mean?

It means the same prime factor is multiplied several times — 2³ is shorthand for 2×2×2.

Q5. Is my input sent to a server?

No. All calculations happen entirely in your browser and are never sent to or stored on a server.
