ballast factor (BF) - The ratio of the light output of a fluorescent lamp or lamps operated on a ballast to the light output of the lamp(s) operated on a standard (reference) ballast. Ballast factor depends on both the ballast and the lamp type; a single ballast can have several ballast factors depending on lamp type. compact fluorescent lamp (CFL) - A family of single-ended fluorescent-discharge light sources with small-diameter [16-millimeter (5/8-inch) or less] tubes.
The factors of 18 are: 1, 2, 3, 6, 9, 18. The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, 24. The common factors of 18 and 24 are: 1, 2, 3, 6. The greatest common factors(gcf) of 18 and 24 is 6. Greatest Common Factor (GCF) = 6.
