Emma plays with her square unit tiles by arranging all of them into different shaped rectangular figures. (For example, a 5 by 7 rectangle would use 35 tiles and would be considered the same rectangle as a 7 by 5 rectangle). Emma can form exactly ten different such rectangular figures that each use all of her tiles. What is the least number of tiles Emma could have?
