Extract

The object of this paper is to complete the proof of the

Theorem. Let P(√d) be the quadratic field of discriminant d > 0. Then Euclid's algorithm does not hold in P(√d) if d is sufficiently large.

We say that u is a quadratic residue mod v in the naive sense, if the congruence y 2u (mod v) has a solution.

Vinogradov, , Trans. Amer. Math. Soc. 29 (1927), 218–26Google Scholar proved His proof is easily generalized to obtain Lemma 3. See also Erdös and Ko, loc. cit. Lemma 3.

It may, of course, happen that a 1 and a 2 are both residues.
