Avideo game has three villains who appear on screen at different intervals. one villain appears every 5 seconds, a second villain appears every 10 seconds, and a third villain appears every 16 seconds. how much time passes between occasions when all three villains appear at the same time?

find the least common multiple of the 3 times, 5 seconds, 10 second, 16 seconds.

 the LCM = 80

 so they would appear at the same time every 80 seconds
