If you're talking about adoptable storage, then the encryption key is lost during the factory reset, so you can't do anything, sorry

If you had encrypted your phone and the SD card, but then proceeded to do a factory reset, sorry but it's lost. There's a reason why encryption is a security measure... if it was that easy to bypass, it wouldn't be worth doing. That's the whole point of encryption.

As such, all you can do is essentially just format the card, either through the phone or by putting it in a PC to do so.

 

Edit : Wait, you said samsung, there might be some hope.
