This is a tedious problem, not a difficult one - there is no short way to eliminate enough of the possibilities to make it any fun. Narrow down first digit to a 1 or 2, 5 can't be a unit digit, and just keep trudging through this yawner.
Now that I saw the hint, it appears to be designed to use the hint... I guess I should have looked first.
In you hint the answer ends in 245 whereas in your answer ends in 254. How come this deficiency?
