I have pulled a 747 out of a hangar myself with a small group of people (like 15 to 20 maybe). It's not brute force needed. The main problem is to control some super soft force application at the right spots (senior engineer advice needed) and to have wingwalkers plus somebody in the cockpit listening and ready to brake and stear as things can get very expensive in a second. Plus some aircraft wheel chocks and somebody ready to position them. Once it gets moving it is hard to stop. For an Embraer it should work a little easier.
