Answer:
They will toll together at their LCM
They will toll together after 3240 seconds
Step-by-step explanation:
We will find the LCM of 36, 45, 72, 81, 108
Do prime Factorization of these numbers and then to get LCM multiply the highest powers of all numbers which appear in prime Factorization.
The LCM of 36,45,72,81 and 108 is 3240
Therefore the bells will toll together after 3240 seconds.
