Calculating the Equilibrium Constant for Reaction

If the following data is "true":

H3PO4(aq)<--> H^+(aq) + H2PO4^-(aq) ...... .Ka1 = 7.5x10^-3
H2PO4^-(aq)<--> H+(aq) + HPO4^-2(aq) .............Ka2 = 6.2x10^-8
HPO4^-2(aq) <--> H+(aq) + HPO4^-3(aq) ............Ka3 = 4.8x10^-13

What is Ka for the reaction H3PO4(aq) <--> 3H^+(aq) + PO4^-3(aq)?
