GCD Over A Ring and Over Its Field of Fractions
In this section, we consider polynomials over a unique factorization domain R, typically the ring of the integers, and over its field of fractions F, typically the field of the rational numbers, and we denote R and F the rings of polynomials in a set of variables over these rings.

... In the previous section we have seen that the GCD of polynomials in R may be deduced from GCD's in R and in F ... proof shows that this allows to prove the existence of GCD's in R, if they exist in R and in F ... In particular, if GCD's exist in R, and if X is reduced to one variable, this proves that GCD's exist in R (Euclid's algorithm proves the existence of GCD's in F) ...
Famous quotes containing the words field and/or ring:
“The field of the poor may yield much food, but it is swept away through injustice.”
—Bible: Hebrew, Proverbs 13:23.
“What is a novel? I say: an invented story. At the same time a story which, though invented has the power to ring true. True to what? True to life as the reader knows life to be or, it may be, feels life to be. And I mean the adult, the grown-up reader. Such a reader has outgrown fairy tales, and we do not want the fantastic and the impossible. So I say to you that a novel must stand up to the adult tests of reality.”
—Elizabeth Bowen (18991973)
