The greatest common factor for the numbers 27 and 81 are 27.
gcf(81, 36) = 9 gcf(27, 54) = 27 gcf(81, 36, 27, 54) = 9
GCF = 9
The GCF is 9.The GCF is 9.
The GCF is 9.
The GCF is 9.
9(9 + 3) = (9 x 9) + (3 x 9) = 12 x 9 = 108
There is no gcf. The factors of 81 are 1, 3, 9, 27, and 81. 3, 9, 27, and 81 do not go into 256 evenly. Therefore, there are no common factors.
It is: 9
81, as it is the highest factor of 81 (81 and 1) and is also a factor of 162 (81 and 2)
It 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.
