Four bells toll at intervals of 8,9,12 and 15 minutes respectively . lf they toll together at 3:00 pm when will they toll together next?​

Answer 1

Answer:

We need to find the LCM of 8 9 12 and 15

8 = 2x2x2

9 = 3x3

12 = 2x2x3

15 = 3x5

LCM = 2x2x2x3x3x5 = 360 seconds

All 4 bells will toll together after every 360 seconds
