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
it took me 5 sec to arrive at 37
if I find a smaller number I'll post a new solution
REM: ORIGINALLY I PUY 53 AND THEN (stupid!!) "corrected " to 37
5 sec is good enough - the rest is tragedy..
.... not to be carried away
