[URL="http://primes.utm.edu/primes/page.php?id=92632"]353*2^1114356-1[/URL] is prime! This is [URL="http://primes.utm.edu/bios/page.php?id=1389"]my[/URL] largest prime by almost 100k digits, which was 50k more digits than the largest one below that, and obviously this is also my first megabit prime. :smile: Amazing what a difference a quad i5 makes compared to a dual-core Athlon!

... and with about 40,000 digits more than the greatest prime found with LLRnet/PRPnet for NPLB so far!
Congrats!

So this is now the new No.1 of the biggest primes here. (The next 7 places are mine! :grin:)

Not sure if you're aware of this, but I found this on a private PRPnet server, run on my quad and only accessed by my quad. So then this is NPLB's second largest prime yet, and the largest found on an LLRnet/PRPnet server (and is 40k digits more than the largest found on a public LLRnet/PRPnet server).

And BTW I have it set up to export its results to the NPLB DB every night. So this prime will be appearing in the NPLB DB around midnight CDT.

Yep, I know. I'll process the result-files the next days.

413*2^786824-1 is prime

Congrats on a huge prime Tim! Much bigger than my largest! :smile:

Indeed, it's NPLB's second-largest prime overall--second only to Cruelty's [URL="http://primes.utm.edu/primes/page.php?id=89030"]311*2^1581686-1[/URL], which was found in "extended" searching beyond the end of our first indivdiual-k drive (effectively, in the current one).
