How to solve Work->Break->Work pattern questions?

Machine/Person A: Works for 20 hours and take break for 4 hours (repeated cycle) Machine/Person B: Works for 40 hours and take break for 8 hours (repeated cycle) In X amount of hours ( say x is 24*7= a week ) starting at same time how many days do both machines/person are at break at the same time? Currently I'm solving them by trying out all option but would like to know if there is a faster way to do them. I'm suspecting that you need to find the least common multiple of some sort. Any help is appreciated
