Index number

If there are two events. Event 1 takes place every 4 yrs and event 2 takes place every 6 yrs. In 2006 both events took place at the same time. when will be the next time they took place together?
Question asked by: mbs_197

2006 they occur together, so when next? One way is just to write out series for +4 and +6, but the easiest way is to find the lowest number divisible by both 4 and 6, which is 12, so the answer is 2006 + 12 = 2018.
