Question

At the flower show, one trolley arrives every 4 minutes to take people to the rose pavilion. Another trolley arrives every 10 minutes to take people to the exotic flower greenhouse. Both trollies just arrived at the main building. How many minutes from now will be the next time the trollies arrive at the main building together?

Answer 1

You have to find the least common multiple of 4 minutes and 10 minutes.

The first step to find the least commom multiple is to find the prime factors of the numbers:

4 = 2*2 = 2^2

10 = 2 * 5.

The next step is multiply the common and non common factors each raised to the greatest exponent with which they appear: (2^2) * 5 = 4 * 5 = 20.

So, the least common multiple is 20, which tells that it has to pass 20 minutes for that both trollies arrive together at the main building again.

Answer: 20 minutes
