the first 10 ten terms of this sequence, which of the following is the greatest factor of x?

I think you need a little bit more information here. For one thing, you didn't include answer choices. For another, "the greatest factor of x" would simply be x itself, which would require you to find the actual value of that product. We know that the GMAT doesn't actually require us to do that much computation! That would be a really big, ugly number. Are you sure the question didn't say "greatest prime factor"?

Where did you get this question?
