That's my calculation, too. I took the five from Harry's room, doubled it for the girls, and multiplied with 4 houses and 7 classes: 280! If the average occupancy was 8, it would result in 448.
It cannot be more for two reasons: There is no evidence for such a large group. Fred and George are sharing the room with Lee Jordan, but no one else I can remember, let alone eight! The other reason is the number of students in the classes: The few teachers we know of could not handle it.
