"As of August 2017, the largest known prime number is 274,207,281 − 1, a number with 22,338,618 digits. It was found in January 2016 by the Great Internet Mersenne Prime Search (GIMPS).

Euclid proved that there is no largest prime number, and many mathematicians and hobbyists continue to search for large prime numbers.

Many of the largest known primes are Mersenne primes. As of January 2017, the six largest known primes are Mersenne primes. [1] The last 16 record primes were Mersenne primes.[2][3]

The fast Fourier transform implementation of the Lucas–Lehmer primality test for Mersenne numbers is fast compared to other known primality tests for other kinds of numbers."
