Let $$\gcd (k,j)$$ gcd ( k , j ) be the greatest common divisor of the integers k and j . For any arithmetic function f , we establish several asymptotic formulas for weighted averages of gcd-sum functions with weight concerning logarithms, that is \begin{aligned} \sum _{k\le x}\frac{1}{k} \sum _{j=1}^{k}f(\gcd (k,j)) \log j. \end{aligned} ∑ k ≤ x 1 k ∑ j = 1 k f ( gcd ( k , j ) ) log j . More precisely, we give asymptotic formulas for various multiplicative functions such as f=\mathrm… Expand
