We study the irrational factor function I(n) introduced by Atanassov and defined by \( I(n) = \prod\nolimits_{\nu = 1}^k {p_\nu ^{1/\alpha _\nu } } \) , where \( n = \prod\nolimits_{\nu = 1}^k {p_\nu ^{\alpha _\nu } } \) is the prime factorization of n. We show that the sequence {G(n)/n} n≧1, where G(n) = Π ν=1 n I(ν)1/n , is convergent; this answers a question of Panaitopol. We also establish asymptotic formulas for averages of the function I(n).
