Vanessa, Joelle and Xandra were each given a piece of streamer of equal length. Vanessa cut hers into equal lengths of 3 cm, Joelle cut hers into equal lengths of 8 cm, and Xandra cut hers into equal lengths of 9 cm. If there were no remainder in each case, find the shortest length of streamer given to each of them.
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72
Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72
Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72
