The greatest common factor (GCF) of 135 and 441 is 27. To find the GCF, you need to determine the prime factors of each number. The prime factors of 135 are 3 x 3 x 3 x 5, and the prime factors of 441 are 3 x 3 x 7 x 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 3 x 3 = 27.
