The factors of 81 are 1, 3, 9, 27, and 81. There is no common factor for a single number; a common factor is a factor of two or more given numbers. The Greatest Common Factor (GCF) is the largest factor common to two or more given numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
