Abstract
In this note, we derive an explicit formula for the equitable chromatic num ber of a complete n-partite graph Kp(1),p(2),....,p(n). Namely, if M is the largest integer such that p(i) (mod M) < [pi/M] (i = 1, 2,...,n) then chie(Kp(1),p(2),...,p(n)) = Sigma (i=1 n) [pi/M + 1], where chi (e)(G) is the equitable chromatic number of graph G.
