# Megaprime

A **Megaprime** is a prime number whose decimal representation has 1,000,000 or more digits. There are infinitely many megaprimes because there are infinitely primes. In fact, since there are only finitely many natural numbers with less than 1 000 000 digits, "nearly all" primes are megaprimes.

As of present (Feb. 2019), 441 megaprimes are known, of those, 14 are Mersenne primes. The current list is avalable here.
