A room is 480 centimeters wide and 520 centimeters long. If n identical square tiles are arranged in a grid pattern so as to cover the entire floor of the room, what is the value of n?

1) A whole number of tiles fit exactly along the length and width of the room, and no tiles had to be cut in order to cover the entire floor.
2) 12 tiles placed adjacent to one another span the width of the room

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
