Let be the set of all positive integers n such that the denominator of 1+1/2++1/n is less than the least common multiple of 1,2,,n. In this paper, under a certain assumption on linear independence, we prove that the set has the upper asymptotic density 1. The assumption follows from Schanuel’s conjecture.
