If you want numbers that are divisible by 2 *or* 6, then that is all 
even numbers.  If you want numbers that are divisible by 2 *and* 6, then 
that you really need only to check multiples of 6.  Why can't you use 
something like this:

6.step(1000, 6)

You need only start with 6 to find multiples.  Every sixth number will 
be a multiple.
