Question

A video 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?

Answer 1

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
