We implement a method to study the large interaction strength limit for different short- and long-range interaction potentials that allows to obtain the exact entanglement spectrum and several entropies. We show that for long-range interactions, the von Neumann, min-entropy and the family of R\\'enyi entropies remain finite for the anisotropic traps and diverge logarithmically for the isotropic traps.
