fewest = 40/10 = 4
most = 40/5 = 8
-------------------------
{2}One radio station broadcast a weather forecast every 18 minutes and another station broadcasts a commercial every 15 minutes. If the stations broadcast both a weather forecast and a commercial at noon, when is the next time that both will be broadcast at the same time?

18 = 2*3^2
15 = 3*5
----
lcm = 2*3^2*5 = 90 minutes
next time = noon + (90/60)hrs = noon + 1.5 hrs = 1:30PM
