Answer:

find LCM of 2,4,6,8,10,12

Answer 2

Answer:

First lets take out the LCM of these values that represent thier common ringing times.

LCM = 360 min

This implies that after every 360 min i.e. 6 hours they toll together. hence in 30 hours they will toll

30 / 6 = 5 times

HENCE THE BELL RINGS 5 TIMES IN 30 HOURS
