The LCM of 4 and 6 is 12
The LCM of 12 and 8 is 24
The LCM of 24 and 10 is 120
The LCM of 120 and 12 is 120
-------------------------------------------------------
This all shows that the LCM of 2, 4, 6,8 10,12 is 120
It will take 120 minutes for the 6 devices to beep together once again. They will beep together every 120 minutes.
