8 = 2³
10 = 2*5
12 = 2²*3

LCM = 2³*3*5 = 120

They will next beep together at 5 pm.

What an annoying family if they do exist in real life. Fancy carrying so many beepers together in a single storage crate. I wouldn't even wish to know when they will all beep together but instead, I would ask them to turn the beepers off and keep everyone's mind at peace.
