A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common.
One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.
The factors of 18 are 1, 2, 3, 6, 9, and 18.
The factors of 27 are 1, 3, 9, and 27.
The factors of 81 are 1, 3, 9, 27, and 81.
The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.

GCM 27 AND 72?
The Greatest Common Factor (GCF) is: 9 .The greatest common multiple of any set of integers is infinite.
What is the greatest common factor of 16 and 27?
The numbers 16 and 27 don't have any common prime factors. 16 = 2 x 2 x 2 x 2 27 = 3 x 3 x 3 Therefore, the numbers are relatively prime and their greatest common factor is 1. Another way to approach this is to look at the difference between 16 and 27, which is 11. The greatest common factor of two numbers cannot be larger than the difference between the two numbers. The greatest common factor of two numbers must also be a factor of the difference between the numbers. The difference, 11, is a prime number, so the greatest common factor must be either 11 or 1. Since the numbers are not evenly divisible by 11, so the greatest common factor is 1.
