Jimmy's solution is nice, and fast as well. It answers the question that
was posed, but I usually like to list the resulting numbers, just as a
check.
Of course, it's easy to get the resulting numbers using Jimmy's approach
(which is also faster than the bulk elimination approach.)
a#~*24|a=.60*i.>:<.1000%60
60 180 300 420 540 660 780 900
