Jenny does the dishes every third day mark every fourth day and misty every sixth day if they all shared dish duty today when will they all share dish duty again?

Look at the multiples of these numbers.
3, 6, 9, 12, 15, 18, 21, 24
4, 8, 12, 15, etc.
6, 12, 18, etc.
What is the smallest multiple that the three share?
