    Erdős Problem #1054: declared status 'open'. Formalized: yes. Let f(n)f(n) be the minimal integer mm such that nn is the sum of the kk smallest divisors of mm for some k1k\geq 1. Is it true that f(n)=o(n)f(n)=o(n)? Or is this true only for almost all nn, and lim supf(n)/n=\limsup f(n)/n=\infty? Current best: The function f(n)f(n) is undefined for n=2n=2 and n=5n=5, but is likely well-defined for all n6n\geq 6 (which would follow from a strong form of Goldbach's conjecture). Prize: no. OEIS: A167485. Tags: divisors, number theory.
