Relative Impact on Global Warming: CO2, CH4, N20, F-Gases

I see various breaks downs of greenhouse gases with CO2 being the largest. BUT then I see GWP estimates for each that suggests that F-gases and N20 although smaller piece of the piece of the pie have a much greater Global Warming Potential. Am I misreading the data? Is there research that shows the GWP potential X Greenhouse Gas Share = total share of global warming?
