The GCF of 21 and 35 is 7.The factors of 21 are 1, 3, 7, and 21The factors of 35 are 1, 5, 7, and 35The greatest (largest) factor common to both 21 and 35 is 7The GCF is 7.

The GCF is 7.

The greatest common factor (or greatest common divisor) of 35 and 84 is 7.

The greatest common factor of 10 and 35 is 5.

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 35, 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 10 and 35 are 1 and 5; the greatest common factor is 5. The common factors of 21 and 35 are 1 and 7; the greatest common factor is 7. The common factors of 35 and 45 are 1 and 5; the greatest common factor is 5. The common factors of 35 and 49 are 1 and 7; the greatest common factor is 7. The common factors of 35 and 61 are only 1; the greatest common factor is 1.
