About prime numbers

What makes a number prime

A prime has exactly two divisors: 1 and itself. 2, 3, 5, 7 and 11 are prime; 9 is not, because 3 × 3 = 9. The number 2 is the only even prime, and 1 is not considered prime.

How paging works

Primes are numbered in order: 2 is the 1st prime, 3 the 2nd, 5 the 3rd. With a page size of 200, the first page shows primes 1 to 200 and the next arrow shows 201 to 400. Changing the page size always returns you to the first page.

How the download works

The download button saves the primes of the page you are viewing as a plain TXT file, built in your browser. Nothing is uploaded.
