Are you looking for the largest known primes?  Lists of records?  Information on who finds the biggest primes (and how?)  You are at the right place!  Here we keep the list of the 5000 largest known primes, updated hourly (hundreds of new primes are submitted every month).  We are the world's primary source to the current prime number records.

  1. The current list of primes
  2. Background information
  3. Tell me more!
Note: these are the largest known primes--so they are very big (most have hundreds of thousands of digits!)  If you want smaller primes, say the first ten thousand primes or first hundred million primes, see lists of small primes.
