Use synthetic division for Rational Roots Theorem and examine only the positive possible roots. You are also only interested in the possible roots less than 180 (just a guess).
I found only this:
_______8______|_______1______3_______2_______-720
______________|
______________|
______________|_____________8_______88_______720
______________|________________________________________
_____________________1______11_______90________0
One of the binomial factors is for a root of 8. This is the only rational root found (used a graph to check).
Your three whole numbers are 8, 9, 10.
