The least common factor of 27 and 81, or of any set of integers, is 1
The Lcm of 27 and 81 is 81, and the GCF of 27 and 81 is 27
GCF = 27 LCM = 81 81 is the LCM of 27 and 81
The Greatest Common Factor (GCF) of (27,81) is 27 and the LCM is 81.
The factors of 81 are 1, 3, 9, 27, and 81. The factors of 243 are 1, 3, 9, 27, 81, and 243. The common factors of 81 and 243 are 1, 3, 9, 27, and 81. Therefore, the least common factor (the smallest common factor) is 1.
The highest common factor of 81 and 27 is 27
The GCF is 27. The LCM is 81.
Since 27 is a factor of 81, all of its factors are common.
Assuming that least common refers to the least common multiple, LCM(27, 81) = 81
The GCF is 27.The greatest common factor of the numbers 108 and 81 is 27.
Since 27 is a factor of 81, it is automatically the GCF.
The greatest common factor of 81 and 189 is 27.
The greatest common factor of 81 and 135 is 27.
