Raeann, Sarah and Penelope were each given a piece of string of equal length. Raeann cut hers into equal lengths of 4 cm, Sarah cut hers into equal lengths of 6 cm, and Penelope cut hers into equal lengths of 10 cm. If there were no remainder in each case, find the shortest length of string given to each of them.
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60
Multiples of 10: 10, 20, 30, 40, 50, 60
