The number of weeks later would be the lowest common multiple of 4,8,12 and 16.
That number would have to have as prime factors at least four 2's, and one 3. That means the ships return together
2^4 x 3 = ? weeks later.
Assume it is not a leap year
so the answer is 48 but how many days was in the year; with leep years
What is 48 weeks after Janaury 2?
1953 was not a leap year.
You do the counting. Don't use a 2008 calendar.
