multi-divideable numbers

the numbers below are particularly great because
(i) they each involve all of the digits (0 to 9) and
(b) they divide by all the numbers from 1 up to 18

so students can be set tasks involving a long number divided by a much shorter one - of your or their choice

what is the hcf of these numbers?
