Dan's Deli makes a club sandwhich every 6 minutes and roast beef sandwhich every 14 minutes. If both sandwhiches were just made, how many minutes will pass before they make then both again at the same time?

Answer:

In 42 minutes

Explanation:

Multiples of 14: 14, 28, 42, 56, 70, 84

Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54

We have to find the LCM.

The LCM is 42. So it takes 42 minutes to be made at the same time again.
