Seven guests at a restaurant came,
The first every day,
The second every other day,
The third every third day,
and so on to
the seventh who came once a week.
When will they all come to dine at the restaurant on the same day?
(What is the smallest number of days?)

I think all you need to do is to find their LCM:

 

LCM[1, 2, 3, 4, 5, 6, 7] =420 days - when ALL 7 can dine together.
