The 100 doors puzzle / Hard Interview Riddle

There are 100 doors and 100 people. The doors have two states (open/closed). All the doors are closed at first. Then the first person opens all the doors, the second person toggles the doors in multiples of 2 (e.g. door 2,4,6..). The third person toggles the doors in multiples of 3 (3,6,9...). This continues until person 100 toggles the door 100.
How many doors are open and how many are closed.
