An acronym for Greatest Common Factor, the largest number that is a common factor of two or more numbers. This provides a working basis of numeric calculation which applies to those numbers. The number derived as the GCF can be used as a simple divisor, which is particularly useful when dealing with large numbers or calculations which are done more efficiently in a simplified form, particularly if elements of the numerical sets must be further developed for application.
Examples of GCF:
Set: 16, 24, 124, 72, 88, 96, 104, 148, the GCF is 4.|
Set: 126, 285, 1011, 292, the GCF is 3.
