Feb 14 at 18:50 comment added Benjamin Steinberg You can find invertible over the integers matrices P,Q with PAQ in smith normal form. So if R is a right inverse to PAQ, then QRP^{-1} should be a right inverse to A
Feb 14 at 14:51 comment added user61388 This is correct. Can I then read the right inverse off of the matrices I would then use to compute the Smith Normal Form?
Feb 13 at 21:32 comment added Benjamin Steinberg Is it not just that the Smith normal form of A is the identity matrix followed by some zero columns?
