List of prime numbers

This is an incomplete list that may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.

A prime number is a number that cannot be divided by a number other than 1 and itself. By Euclid's theorem, there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes. The first 500 primes are listed below, followed by lists of notable types of prime numbers in alphabetical order, giving their respective first terms.

The first 500 prime numbers

The following table lists the first 500 primes; 20 columns of consecutive primes in each of the 25 rows.^[1]

(sequence A000040 in OEIS).

The Goldbach conjecture verification project reports that it has computed all primes below 4×10¹⁸.^[2] That means 95,676,260,903,887,607 primes^[3] (nearly 10¹⁷), but they were not stored. There are known formulae to evaluate the prime-counting function (the number of primes below a given value) faster than computing the primes. This has been used to compute that there are 1,925,320,391,606,803,968,923 primes (roughly 2×10²¹) below 10²³. A different computation found that there are 18,435,599,767,349,200,867,866 primes (roughly 2×10²²) below 10²⁴ if the Riemann hypothesis is true.^[4]
