I don't know quite what it is about the wording of this question that you find ambiguous, but the words 'divisor' and 'factor' mean the same thing in Number Theory. The integer b is a divisor (or factor) of the integer a if a/b is also an integer.sohrabkalra wrote:Dont you think divisor should be replaced by factors for a clear GMAT level problem, coz say in a/b, we call b divisor even though it might not be a factor of A ? or is the language ok according to GMAT standards?
