The greatest common divisor of 63 and 81 is nine (9).

The greatest common factor of 63, 81, and 99 is 9.The prime factorization of 63 is 7*9.The prime factorization of 81 is 9*9.The prime factorization of 99 is 11*9.Thus, the greatest of the common factors of 9.

Answer: 9One way to determine the greatest common factor is to find all the factors of the numbers and compare them. Following will be a quality mathematics help regarding factors: The factors of 63 are 1, 3, 7, 9, 21, and 63.The factors of 81 are 1, 3, 9, 27, and 81.The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 63 are 3, 3, and 7.The prime factors of 81 are 3, 3, 3, and 3.The prime factors in common are 3 and 3, so the greatest common factor is 9.Comparing the prime factors using exponents:63 = 3^2 x 781 = 3^4 = 3^2 x 3^2Then GCF is 3^2 = 9The GCF is 9.The GCF is 9.The GCF of 63 and 81 is 9the GCF of 63 and 81 is 9The Greatest Common Factor (GCF) is: 9

Factors of 63: 1, 3, 7, 9, 21 and 63.Factors of 81: 1, 3, 9, 27 and 81.Common factors are 1, 3 and 9.And another method is by finding the GCF of 63 and 81.The factors of GCF are the common factors of 63 and 81.GCF of 63 and 81 is 9. And factors of 9 are 1, 3 and 9.Instead of writing all factors of 63 and 81 it is better to find GCF and then its factors.

Factors of 45: 1 3 5 9 15 45 Factors of 81: 1 3 927 81 Factors of 63: 1 3 7 9 21 63 The GCF of 45, 81, and 63 is 9

Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.Factors of 63: 1, 3, 7, 9, 21, 63.Factors of 81: 1, 3, 9, 27, 81.GCF (24, 63, 81) = 3

The greatest common factor of 52 and 81 is 1.

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 81, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 81 are 1, 3, 9, 27, and 81. Examples: The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 20 and 81 are only 1; the greatest common factor is 1. The common factors of 39 and 81 are 1 and 3; the greatest common factor is 3. The common factors of 81 and 243 are 1, 3, 9, 27, and 81; the greatest common factor is 81.
