In this work, generalized Euler's \(\Phi_w \)-function of edge weighted graphs is defined which consists of the sum of the Euler's \(\varphi\)-function of the weight of edges of a graph and we denote it by \(\Phi_w(G)\) and the general form of Euler's \(\Phi_w\)-function of some standard edge weighted graphs is determined. Also, we define the divisor sum \(T_{k_w}\)-function \(T_{k_w}(G)\) of the graph \(G\), which is counting the sum of the sum of the positive divisor \(\sigma_k \)-function for the weighted of edges of a graph \(G\). It is determined a relation between generalized Euler's \(\Phi_w\)-function and generalized divisor sum \(T_{k_w}\)-function of edge weighted graphs.
