1) Find all the 0 to 9 pandigital numbers (without leading zero) that have the largest power of 3 as a factor.

2) One of these numbers has a very interesting property. What is it?

*an x to y pandigital number is an integer that contains all the digits from x to y and only those digits once each, for example 1234 is 1 to 4 pandigital but not 1 to 9 pandigital*

(In reply to Uncertain by ed bottemiller)

I have to apologize, I made a mistake in my solution.  I somehow missed finding the pandigital that has 3^15 as a factor.  And so the second question is thus based on all the pandigitals that have 3^14 as a factor.
