Integers with large practical component

Andreas Weingartner

A positive integer $n$ is called practical if all integers between $1$ and $n$ can be written as a sum of distinct divisors of $n$ . We give an asymptotic estimate for the number of…

Practical numbers and the distribution of divisors

Andreas Weingartner

An integer $n$ is called practical if every $m \leq n$ can be written as a sum of distinct divisors of $n$ . We show that the number of practical numbers below $x$ is asymptotic to $c…
