Silliness The next prime number

Bikeridr · 09-05-2011, 03:43 PM

Post here the next-in-line prime number.

Rule is simple:
1.) One prime per post.
2.) Preferrably no two posts in a row (by the same person).
3.) The prime has to be correct and in sequence.

To get a little head start we will begin with the 9.593rd prime which is the first one after 100.000. The number is:
100.003

Let's see how far we can reach. I've made a small C++ program that calculated some 203.000.000 primes which was up in the 4.000.000.000-and-something. (I'll reveal it when we reach that number)

100,019 I think.

You missed out 100,057. And I'm sorry, but 100,061 is divisible by 13, 43 and 179.

Bikeridr · 09-06-2011, 06:19 AM

Indeed. Minus one point to Soltaire1.
Next: 100.069

100,103

Yes, indeed I did. A typo, now fixed - thanks.

100,129 is next.

Bikeridr · 09-06-2011, 07:09 AM

100.151
(Hint: Next is close)

pdurrant · 09-06-2011, 07:16 AM

100,153 — our first prime pair.

Bikeridr · 09-06-2011, 10:03 AM

Well, there are quite a few before, being 2 and 3 the only *true* pair. Anyway, the first pair over 100.000. So, when do we hit the next?

100.169

pdurrant · 09-06-2011, 10:20 AM

100,183

A while yet, I think, to the next pair.
