A 275 BCE Greek n/45 table scaled 44 rational numbers by LCMs 1, 2 and 4. LCM 1 was used 8 times, LCM 2 30 times, and LCM 4 six times. The n/45 series were recorded in ciphered Greek letters. The best clue to the computation method cited alternate n/p series. Alternatives series were listed as many as five times. Additional clues were offered by 1,500 year older Egyptian texts, and 1,000 year later Coptic texts. Overall the scaling method began around 2,000 BCE and ended around 800 AD, about 2,800 years in total.
