Default What are relative primes?

When i got to Stage 2 of P-1 factoring it said that it was processing relative primes. (480) What does that mean?

Two numbers are said to be relatively prime if they have no factors in common, i.e. their greatest common divisor is 1.

It means that before asking multiple questions, you should read a bit. For instance the part about The Math under the "More Information/Help" menu on the Primenet server. It is always a good thing also to browse the previous posts on a forum before starting asking questions (or even posting I would add.) Most of the time the answers are already there and it trains you on how the forum lives and where to find what. If, after doing some research (wikipedia and search engines can be helpful !), you can't find or understand something it might be the time to ask.

The answer given in post #2 was much more helpful to me (and probably the OP) than the answer given in post #3. Not to mention a lot shorter.

There has to be a happy medium in there somewhere. People around here have gotten really sensitive lately. My point is that it really is OK to answer questions. Many readers like myself can benefit from it.

"just to say it is a pity that those lazy questions do get answers :-("
AMEN!

Over time, patterns emerge, of some new participants making an earnest effort to learn, and others appearing to be helpless or just lazy or feigning it. That is how a lazy/whatever poster exhausts the initial goodwill and patience shown by default. It's especially irritating when the answer is easily found in the reference info, to which pointers have been placed in many threads, or by forum search or even general web search with a well chosen keyword or two, or by use of a dictionary, and they've previously repeatedly been told to use those tools, and still they persist in not doing so, instead originating new threads with repeats of already-answered questions. Anyone posting on the forum is presumed able to read and think. Do that search and reading and thought first. Say so when posting a question. In a suitable EXISTING thread.
Very occasionally, such questions draw attention to a gap or ambiguity in the reference info, which gets addressed.
The questions serve sometimes as feedback on what is not obvious. There is a conflict between making the reference info comprehensive, and too inflated and bulky due to repetition of material available elsewhere including online dictionaries, wikipedia, etc. I was already receiving feedback that the reference info compilation was too large, 100 reference info posts ago.

(Don't act like a four-year-old. Why? Why? Why? ... The four year old has the excuse of being unable to read, and immaturity. What's yours? If you have a brain injury or other medical condition, or are quite young, allowances will be made, if we know of it. A certain minimal level of function is needed to be able to productively participate here. That's not us being cruel, it's just what's so.)

+1

One should be careful to distinguish between lazy and incompetent. The latter deserve answering the first time they are asked.

Generally, if I don't understand a word I would look it up. In a conversation between a few people I might ask the speaker to explain, but not in a conference or forum. On a mathematics related forum the first thing to do is look up the word. The OP is relatively new to the forum, isn't it the right time to tell him to do some research for himself before asking a forum ?

Perhaps the fact that I am not a native speaker, but more or less multilingual makes looking up things more natural for me. (It would be one more reason to try to learn more than one language.)

Doesn't the netiquette say to observe, read and learn before posting ? I see so many new people to GIMPS, asking questions that can be found in the readme file... If only they would read it.

But I might have been a wee bit grumpy.

Hear hear!

I think it's OK if a total newbie asks a question or two when they're just starting out. But... It's when they act like children and refuse to learn for themselves after being told where to read that the problems manifest (IMO).
