You need to find the LCM (Least Common Multiple)

Company A = repeats every 6 mins.
Company B = repeats every 15 mins.

6 = 6, 12, 18, 24, 30
15 = 15, 30

answer: 30 minutes

Easy find the least common product. In this case just take the values 1 through 5 and multiply each by 15 and 6 and the first equal product is your answer. In the end you should get 30 minutes.
