There are 200 lockers in your school, numbered 1 through 200 consecutively. The lockers are all closed to begin. Student #1 walks down the corridor and opens all the lockers that are numbered with a multiple of 1, thereby all the lockers are opened. Student #2 then walks down the corridor and changes the status (closed lockers are opened; open lockers are closed) of all the lockers that are numbered with a multiple of 2 (note that in the case of Student #2, this only involved closing lockers). Student #3 then walks down the corridor and changed the status of all the lockers that are numbered w

    There are 200 lockers in your school, numbered 1 through 200 consecutively. The lockers are all closed to begin. Student #1 walks down the corridor and opens all the lockers that are numbered with a multiple of 1, thereby all the lockers are opened. Student #2 then walks down the corridor and changes the status (closed lockers are opened; open lockers are closed) of all the lockers that are numbered with a multiple of 2 (note that in the case of Student #2, this only involved closing lockers). Student #3 then walks down the corridor and changed the status of all the lockers that are numbered with a multiple of 3. By the end of this scenario, 200 students will have walked down the corridor, in numerical order, with each student changing the status of those lockers that are numbered with a number that is a multiple of the student’s number. At that point, which of the lockers are open? More importantly, why are these lockers open?

    I'll give you a clue. Think about how many factors numbers have. Most numbers have an even number of factors, because ..... But ....... numbers have an odd number of factors because ..... . The lockers with an even number of factors will end up .... and the ones with an odd number will end up .... If you come back, and don;t get that hint, I'll give some more.
