This video teaches how to use factoring (e.g., prime factorizations, finding the greatest common factor of two numbers) to solve questions involving the division of large numbers without using a calculator, as when such problems are found on the "no calculator" section of the SAT. Older viewers may recall learning this trick for the SAT when calculators simply were not allowed on the SAT. This is also the same math you'll find on the GMAT, GRE, CHSPE, CAHSEE, CBEST, CSET, and other standardized tests that test you at a high school level.
