The factors of 27 are:1, 3, 9, 27The factors of 63 are:1, 3, 7, 9, 21, 63The Greatest Common Factor:GCF = 9
Since 9 is a factor of 27, all of its factors are common.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 27, 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. Examples: The common factors of 27 and 29 are only 1; the greatest common factor is 1. The common factors of 27 and 33 are 1 and 3; the greatest common factor is 3. The common factors of 27 and 45 are 1, 3, and 9; the greatest common factor is 9. The common factors of 27 and 81 are 1, 3, 9, and 27; the greatest common factor is 27.
The factors of 15 are: 1, 3, 5, 15.The factors of 27 are: 1, 3, 9, 27.The common factors are: 1, 3.The Greatest Common Factor (GCF) is: 3
The factors of 45 are: 1, 3, 5, 9, 15, 45The factors of 81 are: 1, 3, 9, 27, 81The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
the factors of 9 are 1, 3, and 9 The factors of 27 are 1, 3, 9, and 27. The largest factor they have in common (the largest/greatest common factor) is thus 9
Factors of 9 are 1, 3, and 9 Factors pf 27 are 1, 3, 9 and 27 So the greatest common factor is 9
Factors of 9: 1, 3, 9. Factors of 27: 1, 3, 9, 27. GCF (9, 27) = 9
The greatest common factor (GCF) of 27 and 72 is 9. The common factors of 27 and 72 are 1, 3, and 9. Methods: One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 27 are 1, 3, 9, and 27. The factors of 72 are 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 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 27 are 3, 3, and 3. The prime factors of 72 are 2, 2, 2, 3, and 3. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
The common factors of 27 and 45 are 1, 3, and 9. The greatest common factor of 27 and 45 is 9. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 27 are 1, 3, 9, and 27. The factors of 45 are 1, 3, 5, 9, 15, and 45. 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. To then obtain the common factors, list all the factors of the greatest common factor. The prime factors of 27 are 3, 3, and 3. The prime factors of 45 are 3, 3, and 5. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
The greatest common factor of 18 and 27 is 9.The common factors of 18 and 27 are 1, 3, and 9.Methods:One way is to make an educated guess. If you recognize that both numbers are divisible by 9, check whether the corresponding factors of the factor pairs have common factors. Note: When the sum of the digits of a number add up to 9 or a multiple of 9, that number is divisible by 9.9 x 3 = 27Since the corresponding factors of the factor pairs, 2 and 3, do not have any common factors, the greatest common factor is 9.Another way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 27 are 1, 3, 9, and 27.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 18 are 2, 3, and 3.The prime factors of 27 are 3, 3, and 3.The prime factors they have in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
The factors of 27 are:1, 3, 9, 27The factors of 63 are:1, 3, 7, 9, 21, 63The Greatest Common Factor:GCF = 9
The GCF is 9.
The GCF is 9.
The GCF is 9.
The GCF is 9.
Since 9 is a factor of 27, all of its factors are common.
