Claim. J. Jiménez-Urroz, A note on a conjecture of Erdős and Rosenfeld, J. Number Theory 78 (1999), no. 1, 140--143, proves that for every positive integer kk there is a set KK of kk positive integers with ∣⋂n∈KD(n)∣≥3\lvert\bigcap_{n\in K}D(n)\rvert\ge3, as the zbMATH review of the paper states it. With k=3k=3 this answers [[problems/divisors/E0885/_index|Problem 885]] yes for k=3k=3, and it raises the two shared values of Erdős and Rosenfeld's Proposition 3.2 (claim page) to three for every kk. The page is dated by the September 1999 issue.

Covers. The instance k=3k=3.

Depends on. No page of this wiki.

Acceptance. Refereed: Journal of Number Theory. The site labels the problem OPEN, so its commentary crediting the paper is not acceptance.
