Integers with large practical component

Number Theory 2015-06-26 v2

Abstract

A positive integer nn is called practical if all integers between 11 and nn can be written as a sum of distinct divisors of nn. We give an asymptotic estimate for the number of integers x\le x which have a practical divisor y\ge y.
