The nth Prime Page will now find any of the first 2,623,557,157,654,233 primes or π(x) for x up to 100,000,000,000,000,000.

Before primes are added to the List of Largest Known Primes, they must be first be verified, comments must be checked and they must meet the size requirements.  Below we show the status of these primes (if any) that are awaiting verificiation (of any age) as well as those modified (for any reason) in the last 96 hours.  Click on the prime's id for more detailed information.  The color code is at the bottom of the page.

We at the Prime Pages attempt to keep a list of the 5000 largest known primes plus a few each of certain selected archivable forms.  To make the top 5000 today a prime must have 388342 digits or meet the size requirements for it's archivable form.  (Query time: 0.002029 seconds.)
