What is the GCF of 54 and 105?

The greatest common factor (GCF) of 54 and 105 is 3. To find the GCF, you need to determine the prime factors of each number. The prime factorization of 54 is 2 * 3^3, and the prime factorization of 105 is 3 * 5 * 7. The GCF is the product of the common prime factors raised to the lowest power, which in this case is 3.


What is the greatest common factor of 12 and 54?

The GCF of 12 and 54 is 6. To find the GCF, write the prime factorizations of each number.The prime factorization of 12 is 2*2*3The prime factorization of 54 is 2*3*3*3The factors in common are 2*3 = 6, so that is the GCF.


What is the Gcf of 54 and 29?

What is the greatest common factor of 54 72 and 81?

The GCF of 54, 72, and 81 is 9.The prime factorization of 54 is 2*3*3*3The prime factorization of 72 is 2*2*2*3*3The prime factorization of 81 is 3*3*3*3The GCF, then, is 3*3 = 9


What is the greatest common factor of 18 54 90?

To find the greatest common factor (GCF) of 18, 54, and 90, we first need to find the prime factorization of each number. The prime factorization of 18 is 2 * 3^2, the prime factorization of 54 is 2 * 3^3, and the prime factorization of 90 is 2 * 3^2 * 5. To find the GCF, we identify the common prime factors among the numbers, which are 2 and 3^2. Therefore, the GCF of 18, 54, and 90 is 2 * 3^2, which equals 18.

What is the GCF of 27 54 and 81?

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.
