Quizplus · Accepted Answer

Since n is a multiple of x, the common factors of n and x include x and any other factor of x. However, we are looking for the greatest common factor, which is simply x. Therefore, answer choice D is correct. The other answer choices are not correct because they either include factors that are not necessarily common to both x and n, or they are not as great as the factor x.
