Solve this: II Arun, Shaji, and Mohit cycle every day along the circular ring road. They take 8, 12, and 16 minutes, respectively, to take a complete round. If all of them start together at the same time from the same place, after how much time will all three of them meet at the same place again?

In this case, we have to find the Lowest Common Multiple of 8, 12 and 16.
8 = 2 X 2 X 2
12= 2 X 2 X 3
16= 2 X 2 X 2 X 2
The L.C.M. is 2 X 2 X 2 X 2 X 3 = 48 [Prime factorisation method]

Therefore all three of them will meet again after 48 minutes of starting together.
