Mean square estimates for the error terms of sums of the greatest common divisor

Abstract We investigate the mean square behavior of error terms that arise in the summation of gcd ( n 1 , … , n k ) $\gcd (n_1,\ldots ,n_k)$ gcd left parenthesis n 1 comma ellipsis comma n Subscript k Baseline right parenthesis with n 1 … n k ≤ x $n_1\ldots n_k \le x$ n 1 ellips...
