Abstract

Given a positive integer n, we let sfp(n) denote the squarefree part of n. We determine all positive integers n for which max{sfp(n),sfp(n + 1),sfp(n + 2)}≤ 150 by relating the problem to finding integral points on elliptic curves. We also prove that there are infinitely many n for which max{sfp(n),sfp(n + 1),sfp(n + 2)} < n1/3. © 2016 World Scientific Publishing Company.
