Summary of the Complementary Divisor Multiplication Method

Summary of the Complementary Divisor Multiplication Method

This page is a re-transcription of s5231a99 that summarizes a method to multiply in sexagesimal and similarly-sized highly divisible number bases by leveraging the pairs of complementary divisors (here called reciprocal divisors). The original name given to the method was the Reciprocal Divisor Method, now called the Complementary Divisor Method. The 6 pairs of sexagesimal complementary divisors appears at the top left. The abbreviated sexagesimal multiplication table appears on the left below the divisor table. Three cases applying the CDM are studied at right. One month later the page was developed into a 100+ page manual (The d7a60, a 6½ megabyte PDF) on how to multiply in bases of the magnitude of sexagesimal through use of an abbreviated multiplication table. This iteration includes a table of sexagesimal argam and their names at right. Full sexagesimal multiplication table in argam, 111k PDF, abbreviated sexagesimal multiplication table 102k PDF.
