Calcudoku Challenge

Every Calcudoku has a single solution that can be reached logically. Fill in the grid such that no two digits repeat in any column or row. Use the shapes in the grid as your guide. Each shape contains a number equaling the product of the shapes' digits.
Currently the 4x4 mode contains a large number of levels, and the 5x5 and 6x6 modes only contain 1 level. Looking forward to more levels in 5x5 and 6x6 modes!
