On 13 November 2017, 00:26:44 UTC, PrimeGrid’s PPS Mega Prime Search project found the Mega Prime:
943*2^3442990+1

The prime is 1,036,447 digits long and will enter Chris Caldwell's The Largest Known Primes Database ranked 208th overall.

The discovery was made by Joshua Charles Campbell (Warp Zero) of Canada using an Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz with 64GB RAM, running Linux. This computer took about 42 minutes to complete the primality test using multithreaded LLR. Joshua is a member of the Canada team.

The prime was verified on 13 November 2017, 18:22:32 UTC by Jon Goral ([KWSN]John Galt 007) of the United States using an Intel(R) Core(TM) i7 940 CPU @ 2.93GHz with 24GB RAM, running Microsoft Windows 10. This computer took about 6 hour 76 minutes to complete the primality test using LLR. Jon is a member of The Knights Who Say Ni! team.

For more details, please see the official announcement.

Hi! I found this prime! I was wondering if there would be anyway to get the decimal representation of it? I know it's over 1M digits, is there any software that can produce it?

You can get the decimal representation directly on the PrimeGrid website.

If you go to your primes page, you'll see a link next to the prime's length. Click where it says decimal.

But to answer your exact question, if you ever want to get the full decimal representation of an arbitrary number, you can use PFGW with the -od command line arguments. For example:

pfgw64 -od -q"943*2^3442990+1"


Congratulations!
