Primes are found in integral domains, not fields. In a field, every nonzero
number has an inverse, which means you can find two other numbers which
multiply to it (as long as the characteristic of the field isn't 2 or 3).

What is "by convention x3" for?

Speaking of domains, what should we call the mathematical terms group, ring,
domain, body, and field? "Body" (corps, Körper) is a term used in French and
German for a division ring, and usually is used instead of "field".
