Apparently you did the same reasoning to come up with that solution. While
thinking about this problem I noticed that two consecutive numbers are
always realtively prime. Obvious, but I had never realized that before. Now
I am wondering about the relationships between numbers separated
by intervals other than one. And what happens if this difference is a prime
number and what happens if it is not.
It seems to me that another problem would be to find a general solution
which runs quickly for very large numbers.
