Fundamentally, PARI was designed for univariate polynomial rings over a field.
They have the property to form an Euclidean domain, so standard Euclid
algorithm applies to a lot of operation (but not factor).

However, factor still generally assume you want to factor univariate polynomial
over a field and will omit the unit.

You can use factorback to recover it.
