Min, Gillian and Jane were each given a piece of rope of equal length. Min cut hers into equal lengths of 3 cm, Gillian cut hers into equal lengths of 6 cm, and Jane cut hers into equal lengths of 10 cm. If there were no remainder in each case, find the shortest length of rope given to each of them.
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
Multiples of 6: 6, 12, 18, 24, 30
Multiples of 10: 10, 20, 30
Shortest length of rope given to each of thecm
= Lowest common multiple of 3 cm, 6 cm and 10 cm
= 30 cm
