Question

Four bells begin tolling together and toll at interval of 2,6,10,14 seconds respectively. After how many seconds they toll together?​

Answer 1

After 210 seconds, the bells will toll together.

Step-by-step explanation:

To find the time after bells will toll again,

Let's find the L.C.M. of 2, 6, 10, 14

The factors would be;

2 = 2 * 1

6 = 2 * 3

10 = 2 * 5

14 = 2 * 7

Since, 2 is the common factors among them, L.C.M of the numbers would be 2 * 1 * 3 * 5 * 7 = 210 sec.

Thus, after 210 sec. the bells will toll together.
