-- "Common" means "same for both". There's no such thing as a common factor
of a single number.
-- Any time you're looking for the "greatest" of something, you only get one of them.
If there were two greatest ones, then you'd want to know which greatest one is
greater than the other greatest one. If anybody heard you asking that, they'd
never talk to you again.
So the question is really pretty useless, in more ways than one.

What are the greatest common factors for 84 and 28?
28
What is the common factor of both 14 and 28?
Since 14 is a factor of 28, all of its factors are common.
What is the greatest common factor of 28 and 77?
The greatest common factor of 28 and 77 is 7.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 28 are 1, 2, 4, 7, 14, and 28.The factors of 77 are 1, 7, 11, and 77.The common factors are 1 and 7. Therefore, the greatest common factor is 7.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 28 are 2, 2, and 7.The prime factors of 77 are 7 and 11.The prime factors in common are a single 7, so the greatest common factor is 7.Summary of results:The common factors are 1 and 7.The greatest common factor is 7.

What what is the greatest common factor 21 and 28?
The GCF of 21 and 28 is 7.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 21 are 1, 3, 7, and 21.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1 and 7. Therefore, the greatest common factor is 7.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 21 are 3 and 7.The prime factors of 28 are 2, 2, and 7.The prime factors in common are a single 7, so the greatest common factor is 7.77There is neither a greatest common factor nor common factors of a single number, such as 2821, 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.
What is the greatest common factor of 24 and 28?
The GCF of 24 and 28 is 4.One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24.The factors of 28 are 1, 2, 4, 7, 14, and 28.The common factors are 1, 2, and 4.Therefore, the greatest common factor is 4.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 24 are 2, 2, 2, and 3.The prime factors of 28 are 2, 2, and 7.The prime factors in common are 2 and 2, so the greatest common factor is 2 x 2 =4.The Greatest Common Factor (GCF) is: 4The greatest common factor of 24 and 28 is 4.
