One tray of granola bars cut into 4 equal size pieces. a second tray was cut into 12 equal size pieces, and a third was cut into 8 equal size pieces. jan wants to continue cutting until all three trays have the same number of pieces. how many pieces will there be on each tray?

4 is really 2 * 2

12 is reallly 2 * 2 * 3

8 is really 2 * 2 * 2

now, the 2 * 2, is repeated in the factoring, so we use it once only.  We still have to account for the extra 2 and 3.

therefore, the LCD will be 2 * 2 * 2 * 3, or 24.

after all the slicing in each tray, all pieces will be equal in length in each tray, and there'll be 24 of them in each tray.
