We study the origin of subharmonic synchronization in arrays consisting of few over-damped Josephson junctions. We show that for asymmetric arrays, the evolution equations contain second (or higher) order derivatives or non-sinusoidal terms, both leading to fractional Shapiro steps in presence of external ac drive .
