the easy way is just to list the sequences of days:
6 12 18 24 ...
8 16 24 ...
and see where they collide.
The general way to do it algebraically is to note that
6 = 2*3
8 = 2^3
The smallest multiple of both 6 and 8 is therefore 2^3 * 3 = 24
together paul & harvey are going to visit their aunt on sunday. If paul visit their aunt every 6 days while harvey every 8 days, on what day will they visit their aunt together?
(With solution pls).. tnx...
