I'm not sure if this is what you are asking (some extra detail and an example or two might help with that) but 3 bits are enough to represent a single value ranging from 0 to 7. 8 such values would take 3*8 = 24 bits, and there are 8 bits per byte in most every modern system, so that's 24/8 = 3 bytes will be enough.
Most applications would use either 8 bits per value (8 bytes total) for ease of programming and for runtime speed, or 4 bits per value (4 bytes total) if library routines for BCD conversion and formatting were available.
