List of prime numbers - wikipedia List of prime numbers This is a dynamic list and may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries. A prime number ( or a prime ) is a natural number greater than 1 that has no positive divisors 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 1000 primes are listed below, followed by lists of notable types of prime numbers in alphabetical order, giving their respective first terms. 1 is neither prime nor composite.

The Goldbach conjecture verification project reports that it has computed all primes below 4 × 10. That means 95,676,260,903,887,607 primes ( nearly 10 ), 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 × 10 ) below 10. A different computation found that there are 18,435,599,767,349,200,867,866 primes ( roughly 2 × 10 ) below 10, if the Riemann hypothesis is true.
