The typical way a newbie would behave is to open a file manager (I guess 
nautilus in Gnome, dolphin in KDE), navigate to a pdf file and click on it. If 
the system is set up by default, in Gnome the file should be associated to (and 
thus opened by) evince, and in KDE by Okular. AFAIK, that is the default. If 
the system config was changed from default to something else, then the user who 
changed it was supposed to be aware what he was doing, and which other app has 
been configured to take care of the pdf files.

In KDE, once you open the pdf file by clicking on it in the file manager, you 
can look up on the titlebar and see the word "Okular", or go to help menu and 
find the "Okular handbook" and "About Okular" menu items. If that still isn't 
enough of a clue about the app's name, you can click on the "About Okular" 
item and read off a whole bunch of information including the name, description, 
version number, list of authors, licencing info, upstream website address, 
etc.

As for Gnome, I don't use it so I cannot tell exactly, but I guess the 
equivalent information can be found in an equivalent place. If not, Gnome devs 
are probably living somewhere in some galaxy far, far away... ;-)

HTH, :-)
