Whats the smallest number ("the magic number") that can satisfy these conditions?
- its positive
- it is not divisible by any number below 20 (excluding 1)
- the average of the digits is an even number between 3 and 9
I was just wondering why 37 could not fill this criteria after reading a solution posted by charlie.
