We have computed gravitational equilibrium sequences for systems consisting of N incompressible fluid bodies (N=3, 4, 5). The component fluids are assumed congruent. The system seems to become a lobe-like shape for N=3 case and a ring-like shape for N≥4 cases according as the fluid bodies come nearer to each other. For every sequence there is a critical equilibrium whose dimensionless angular momentum has the minimum value of the sequence. As the final outcome is nearly in equilibrium in the computation of a collapsing gas cloud, we can apply the present results to the interpretation of these dynamical calculations. For instance, the gas cloud can never fissure into any N-body equilibrium when its dimensionless angular momentum is below the critical value of the N-body sequence.
