 The article states: 

 ""It was described by D. H. Lehmer and R. E. Powers in 1931, and developed as a computer algorithm by Michael A. Morrison and John Brillhart in 1975. 

 ""The continued fraction method is based on Dixon's factorization method."" 

 Ridiculous. If the method was decribed in 1931, then it is not ""based"" on Dixon's factorization method (assuming the 1981 date listed in the WP article is correct). 

 It might be a version of, or related to, Dixon's method. But it certainly is not ""based"" on it.   

 I hope someone knowledgeable about this subject will fix this with appropriate wording.  "
