The factors of 9 are 1, 3 and 9. For them to be common, they need to be compared to another set of factors.
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.
The Greatest Common Factor (GCF) is: 9
The Greatest Common Factor (GCF) is: 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.
The greatest common factor of 9 and 25 is 1
The greatest common factor of 9 , 8 = 1
The greatest common factor of 9 and 620 is 1.
The Greatest Common Factor of 9, 23 is 1.
The greatest common factor of 9 and 618 is 3
It is meaningless to ask "What are the greatest common factor of 9". There should be two or more numbers. Greatest common factor means the greatest number which is the common factor of all the numbers mentioned.
