wire in conduit

I am wiring a new garage, I know that I can 9 #12 wires in 1/2 EMT. I want to run 3 separate circuits. Can I run 3 separate hot wires & use a common wire for the ground & neutral branching them off at separate junction boxes?

If using 3 separate single pole breakers for the 3 circuits then each circuit needs it's own neutral. Ground can be shared. One neutral can be shared between 2 hots on opposite legs but the 2 hots must be on a double pole breaker, this is referred to as a multiwire branch circuit.

Or is this a detached garage? Unless this is an attached garage you cannot run 3 separate circuits to it. You can run one branch circuit or one multiwire branch circuit.
