The Greatest Common Factor (GCF) is: 9
To find the Greatest Common Factor (GCF) of 27, 54, and 81, we need to first find the prime factorization of each number. The prime factorization of 27 is 3 x 3 x 3, the prime factorization of 54 is 2 x 3 x 3 x 3, and the prime factorization of 81 is 3 x 3 x 3 x 3. The GCF is the product of the common prime factors raised to the smallest exponent, which in this case is 3 x 3 x 3 = 27. Therefore, the GCF of 27, 54, and 81 is 27.
