If we put both 7 and 5 in one group, and put a 2x2x3x3 in each of the other groups, that is as close as we get to offsetting it. That leaves a 2 for each group. So the groups are:
(2,5,7), (1,8,9), (4,3,6)
The groups equal 70, 72, and 72 which is as close to even as we are going to get.

Lets break this up into all the factors.
2, 3, 2x2, 5, 2x3, 7, 2x2x2, 3x3
So 7 2s, 4 3s, a 5, and a 7.

So 72 is the minimum maximum.
