I used Chemstation and Enviroquant Chemstation for EPA methods calling for Peak Gaussian Factor and never found a calculation built in for it. It is a different calculation that any of the USP ones. I did it the pen-and-paper way: zoom in on the particular peak with baseline, print it, and get out my ruler and triangle to draw it by hand. There might be a work-around, but I never did find it.

Peak resolution and USP tailing can be found in the Extended Performance Report. I used USP tailing to judge day to day performance, but then did Peak Gaussian Factor to comply with the method.
