(But better to use it only to check your answers.)
As 2 goes into 6, you can narrow the question down to the LCM of 5 and 6. (you could look at two as well but that might be a waste of time)
(2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30)
5, 10, 15, 20, 25, 30.
6, 12, 18, 24, 30.
Therefore 30 is the lowest common multiple.
