Best Answer

Every number except zero is a factor of every other number. Usually this kind of question is intended as a question about integral factors, those that can be paired with another integer to produce the number as a product. In that sense, 9 is not an integral factor of 11, because the paired number with 9 is 11/9, a number that is not an integer.
