There is neither a greatest common factor nor common factors of a single number, such as 9, 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 9 are 1, 3, and 9.
The prime factors of 9 are 3 and 3.
Examples:
The common factors of 9 and 24 are 1 and 3; the greatest common factor is 3.
The common factors of 9 and 64 are only 1; the greatest common factor is 1.
The common factors of 9 and 108 are 1, 3, and 9; the greatest common factor is 9.

What is the greatest common factor for 9?
There is not a greatest common factor of 9 because there cannot be a greatest common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The factors of 9 are 1, 3, and 9. The prime factors of 9 are 3 and 3.
What is the greatest common factor of 9 and 5?
The greatest common factor of 5 and 9 is 1.
What the greatest common factor for 9 and 27?
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
What is the greatest common factor of 7and 9?
The factors of 7 are 1 and 7 The factors of 9 are 1, 3, and 9 So the greatest common factor is 1
Greatest common factors of 72and27?
The Greatest Common Factor (GCF) = 9
What is the greatest common factor of 9 and 12?
The greatest common factor of 9 and 12 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 9 are 3 and 3. The prime factors of 12 are 2, 2, and 3. The prime factors in common are a single 3, so the greatest common factor is 3.
What is the greatest common factor of 27 and 72?
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.
What is the greatest common factor of 2 and 9?
Since 2 is a prime number, either it is the greatest common factor or 1 is. Since 2 is not a factor of 9, the greatest common factor is 1.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 2 are 1 and 2.The factors of 9 are 1, 3, and 9.The only common factor is 1. Therefore, the greatest common factor is 1.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factor of 2 is 2.The prime factors of 9 are 3 and 3.There are no prime factors in common, so the numbers are relatively prime, meaning the greatest common factor is 1.Summary of results:The common factor is 1.The greatest common factor is 1.The numbers are relatively prime.The GCF is 1.The GCF is 1.
What are the greatest common factors of 18 and 45?
The Greatest Common Factor (GCF) is: 9
What are the greatest common factors for 9 and 42?
The greatest common factor (GCF) is 3.
What are the greatest common factors for 6 9 24?
The greatest common factor is 3
What are the greatest common factors of 9 and 25?
Answer:The only common factor of 9 and 25 is 1.The greatest common factor of 9 and 25 is 1.Because 1 is the only common factor, the numbers are relatively prime.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.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 9 are 1, 3, and 9.The factors of 25 are 1, 5, and 25.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.The common factors and greatest common factor can also be calculated by identifying the common prime factors and multiplying them together to identify the greatest common factor, and then taking all the factors of it to determine the common factors.The prime factors of 9 are 3 and 3.The prime factors of 25 are 5 and 5.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
