    Group Prime
In summary: I think I see where this is going.Let's face, it with 13 million figures they could tell us anything. It's not as if we're going to go away and check it.In summary, the mathematicians at UCLA have discovered a 13-million-digit prime number. This makes them eligible for a $100,000 prize.

isn't the obvious enough? not all numbers can be divided by 7 so it gets put into a rather selective category doesn't it? I don't know the exact numbers but something like only 1 in 20 numbers can be divided by 7.

Isn’t every seventh number (starting from seven) divisible by seven? And if you take the product of all the prime numbers, up to and including the so-called “largest prime” and add one to that, this new number is either a prime or it contains a prime larger than the previous largest. The number of primes is therefore infinite.

way to steal vanesch's joke. i award you -7 points.

Bwahahaha ! :smile: I'd think that about 1 number in 7 can be divided by 7
Looks like some folk here haven't done their 7 * table yet.

To be honest, I came here only for the post count.

So Euclid says anyway... but then what does he know :biggrin:

Try harder, posts in GD don't count.

If posts in here counted I'd have several thousand. If they'd let me out of here I'd thousands too.

About three times that, as long as we are in the realm of not exact numbers.
Is this the joke? If so, Borek should get the credit. I thought it was a good one.

This is an amazing discovery. Until now, I thought prime numbers were massless :shy:

edit: oops, ivan made this joke already...

That's okay, some jokes are worth telling twice. :biggrin:

I thought only Catholic numbers have mass.

Why don't they use the computer power for something useful? Calculating massive prime numbers was used to test the computational power of computers, I think they have gone far enough.

Monique, ever hear of Folding@Home?

There are plenty similar projects, don't worry, heh.

Haha, yeah. I totally missed that. That non-exact numbers thing threw me off.

Argh. You've out witted us all.

Maybe I should return to Academic Guidance and tell people what book they need to study linear algebra. That should put me in the 1000s by next week!

Joke? I was deadly serious.

its a joke when Borek says it, but no one had a problem believing I thought 1 in 20 numbers is divisible by 7? I don't know if I should be offended or if this is just another case of "don't feed the tribdog"

Sorry Tribdog, if you had said 2 in 20 numbers were divisible by 7 it would have looked like a joke :smile:

And this post means we've hit the next prime number in this thread!

5 is a very pretty prime =)

yes, post number 51 is a great prime. almost as good as 15,18,21 and 24.

Whaaaa?!? 51 is not prime! But 53...? :biggrin:

DOH! tribdog, you beat me to post # 53!

Dr Pepper has 23 flavors.
Baskin Robbins has 31 flavors.
Boeing has a 757

I wonder what the biggest prime number on a product is?

Prices like $4999 don't count.

I don't have the answer. It's merely the LowlyPion Conjecture.

Good ones. All I could think of was Formula 409.

You see Monique, there is a use for prime numbers. Without cutting edge prime numbers, where would we get prime time TV shows, USDA prime beef, prime real estate locations, and Prime Ministers not to mention exotic composite materials. Look at what happened with subprime loans. Now the gov't is looking to prime the pumps so these numbers will come in very handy. But most importantly, we have to keep one step ahead of the terrorists. What if they had a bigger prime number than we do?
