Can the info be deleted permanently so that nobody recovers it?

[AC Question]

can the info be deleted permanently so that nobody recovers it?

I own an HTC M8 and want to sell my phone, and apart from the usual factory reset, I want to make sure that my personal info is not recovered through a software. Is it possible to completely wipe off my data without the fear of it being recovered ?
Help and suggestion will be highly appreciated!

factory reset, encrypt all storage, copy some rubbish files from your pc to your phone until storage is full 100% then factory reset again.
i usually copy crap like windows dll files
