We study singularity of effective ℚ-divisors on products of projective spaces of multidegree (1,1...,1). This generalizes works of Bath, Mustaţă and Walther on singularity of square-free polynomials. We also give a lower bound on the log canonical threshold of a hypersurface in products of projective spaces.
