Page guide

Check whether a whole number is prime.

How to use Prime number checker
  1. Enter the values you want to calculate and choose the relevant units or settings.
  2. The result updates as you type. Adjust the available settings if needed.
  3. Review the result, then use Copy result or a download link when available.

How to use it

Enter a whole number between 0 and 1 trillion. The checker divides it by possible factors and shows its prime factorization.

A worked example

97 is prime because its only positive divisors are 1 and 97. 91 is not prime: 7 × 13 = 91.

What to know

Zero and one are neither prime nor composite. Inputs must be integers within the stated range. This checker is intended for everyday arithmetic, not cryptographic key validation.
