Apps by google won't update

All of my Google apps won't update. Maps, gmail, keyboard, calendar, etc. None will udate. It says it fails and requires updated SDK. What does this mean?

Personally I would say happy day's,I removed most of me Google apps.
I would start with doing a factory reset,Then they should update.

Did a factory reset and I still get the '[app] requires newer SDK' I still don't know what this means.
