How can I reset my phone to factory defaults

[AC Question]

My phone was stolen, I got it back but my google account was hacked and corrupted. Now I cannot get into my phone. What should I do? Can I reset the phone to factory defaults? I tried creating a new google account but it says I have to use the account that was originally connected to the phone. I can't rememer my password.
