Menon-type identities again: A note on a paper by Li, Kim and Qiao
arXiv:1911.05411 · doi:10.5486/PMD.2020.8786
Abstract
We give common generalizations of the Menon-type identities by Sivaramakrishnan (1969) and Li, Kim, Qiao (2019). Our general identities involve arithmetic functions of several variables, and also contain, as special cases, identities for gcd-sum type functions. We point out a new Menon-type identity concerning the lcm function. We present a simple character free approach for the proof.
