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.
What is the greatest common factor of 18 27 and 63?
The GCF of 18, 27, and 63 is 9. The prime factorization of 18 is 2*3*3 The prime factorization of 27 is 3*3*3 The prime factorization of 63 is 3*3*7 The GCF is 3*3 = 9.
What is the greatest common factor of 18 27 and 99?
The GCF of 18, 27, and 99 is 9. The prime factorization of 18 is 2*3*3. The prime factorization of 27 is 3*3*3 The prime factorization of 99 is 3*3*11 So the GCF = 3*3 = 9.
What is the prime factorization of 27 using the ladder method?
The prime factorization of 27 is 3 x 3 x 3.
What is the GCF of 27 63 81?
To find the Greatest Common Factor (GCF) of 27, 63, and 81, we first need to find the prime factors of each number. The prime factorization of 27 is 3 x 3 x 3, the prime factorization of 63 is 3 x 3 x 7, 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 lowest power they appear in any of the numbers, which in this case is 3 x 3 x 3 = 27. Therefore, the GCF of 27, 63, and 81 is 27.
