First k is 2 ^ 4 x 41 x 557 x 1693 x 3049 x 1 617211
Second k is 2 ^ 3 x 3 x 29 x 47 x 83 x 647 x 3779 x 6577 x 92623

Oh, I misunderstood -- thought 9474...1673 was the P26 -- I didn't count the digits!

Nevermind.

even though V4 LL includes DC.

...that's over 20 GHz-years of GIMPS computing. Over 15 of those GHz-years have come since I switched to v5 about a year ago.

Now the sad news. Someone was mucking around with some of my borged computers, and deleted not just prime95, but the whole darn prime95 folder from three or four of them :( Luckily, they were "nice" enough to only delete the prime95 program itself from the other two or three. But, in the end, I lost four 90%+ tests on 43M exponents (about 6 weeks of work for four cores), as well as about 20% of a 36M test. It was a real bummer. I've reborged the systems - we'll see what happens...

Cool, according to my calculations that amounts to 1.728E21 floating point operations or 1.728 ZettaFlop. (Based on the primenet standard of 2 flop/cycle)

Passed 50,000 P-1 tests, 1,000 successes and 1,000 P-1 GHz-days. All over the weekend.

2 more CPUs exceeded 2,000 Ghz Days.

1,000 DC Ghz Days

You are putting up some impressive numbers. I have a couple of systems that are about to cross the 1,000 GHz-day mark.

Today, I passed over 10,000 total lifetime results. Right now, I'm at 10,002: 9,731 TFs, 93 P-1s, and 178 LLs. 7,730 total GHz-days, or 21.2 GHz-years. I turn 27 tomorrow; I wonder how long before my GIMPS GHz-years surpasses my age.

Looks like one of my borgs was disconnected from the Internet for a while, because it just puked like eight 2^69 factoring results into PrimeNet.

One of them yielded a factor, a very nice present on my (3^3)th birthday:

M62602249 has a factor: 220190613130695160687.

I just took out 24 exponents for LL testing as lucky birthday exponents. They're all 47Ms (consecutive primes, in fact, I think), and I think I'll try to mix them into my regular exponents so that they finish evenly throughout the next year.

Maybe one of them will be the lucky one! Or I'll just have a really easy time figuring out how long until my next birthday (365 - exponent age given by PrimeNet)!
