Android rooting question? 10 points!!?

Okay so recently i rooted my HTC desire 816 and did it successfully. It came with SuperSU however i found out about FolderMount which is awesome because on paper the phone has 8 gigs but in reality it has only 4 and my SD card is 8 gigs but i filled it up already and just ordered a 64 one however i guess what im asking is if i reset my device as in factory reset it, will it remove the root? i dont care about it deleting files and photos and stuff all i care is about the actual root or would i have to do the whole rooting process again?

thanks in advance!

and sorry about the long question:)
