Even i was wondering this. I think it has something to do with progressions or combinatorics. Not sure. Experts please weigh in if there is a simple logic involved. Thanks!

Rest assured that the concept of "coprime integers" (and this suspicious formula) is not required knowledge for the GMAT. Yes, it's conceivable that a GMAT question might test a certain aspect of coprimes, but if it did, the question would include a definition of "coprime."
