Guldin's Factor Table
One of the oldest factor tables, giving factorizations up to 10,000
Paul Guldin made an early factor table up to 10,000 in his 1641 four-book work on mathematics and astronomy De Centro Gravitatis, extending the earlier table from Cataldi.
Swiss Jesuit mathematician and astronomer Paul Guldin made a factor table of odd numbers not divisible by 10 up to 10,000 in the fourth book of his series De Centro Gravitatis in 1641. The table was captioned "tabula ultima," referring to the fact that it is the last table in the last book of his four-volume work. The motivation for the computation and inclusion of this table is not clear based on Guldin's own explanation.
