The corresponding separable approximation for the integral kernels in the three- and four-body kaonic clusters is obtained by using the Hilbert-Schmidt expansion procedure. Different phenomenological models of $\\bar{K}N-\\pi\\Sigma$ potentials with one- and two-pole structure of $\\Lambda$(1405) resonance and separable potential models for $\\bar{K}$-$\\bar{K}$ and nucleon-nucleon interactions, are used.
