How can I tell if a number is a multiple of four using only the logic operator AND?

Question

I\'m messing with assembly language programming and I\'m curious how I could tell if a number is a multiple of 4 using the logic operator AND?

I know how to do it us

Answer 1

A number is a multiple of 4 if its lower 2 bits are 0, so you can simply shift the number right twice and check shifted bits for 0.
