One-loop maximal helicity violating (MHV) amplitudes in N=4 super Yang-Mills(SYM) theories are analyzed, using the prescription of Cachazo, Svrcek, andWitten (CSW). The relations between leading N_c amplitudes A_{n;1} andsub-leading amplitudes A_{n;c} obtained by the CSW prescription are found to beidentical to those obtained from conventional field theory calculations.Combining with existing results, this establishes the validity of the CSWprescription to one-loop in the calculation of MHV amplitudes in N=4 SYMtheories of finite N_c.Comment: Minor changes and typos fixed.
