We show that the largest prime factor of n2 + 1 is infinitely often greater than n1.279. This improves the result of de la Breteche and Drappeau specialIntscript who obtained this with 1.2182 in place of 1.279. The main new ingredients in the proof are a new Type II estimate and using...

On the Maximal Distance of Numbers with a Large Prime Factor 1. Introduction. Let P (x) be the greatest prime factor of the integer∏ x< n≤ x+x1/2 n. It is expected that P (x)≥ x for x≥ 2. However, this inequality seems extremely difficult to verify. In 1969, Ramachandra [...
