I'm pretty certain 3 factory resets would do it but there are some defragment apps on the Google Store that would make quick work of any stray files before the reset.

Not certain, under these circumstances how encrypting would make any difference.

There are deep cleaning apps on Android as an alternative, but unless your device has trade secrets from work, naughty selfies, or other such items, I really don't see the point in using them.

The point behind encrypting the data before you wipe it is this. It's an added layer of security when you're selling off your device. When you encrypt the data, a pin number is required to access it. If you encrypt the data then factory reset the phone, any data that is recovered is useless without the pin number to decrypt it.

Encrypting the existing data before the factory reset will not prevent the new owner from using the device or placing their own data on the user-accessible storage areas. It simply makes the old data virtually unusable.
