There is no Greatest Common Factor (GCF) for a single number. The Greatest Common Factor is the largest factor common to two or more numbers.

850 is not the greatest common factor of 85 and 10. The person answering the question about the numbers with 850 as the greatest common factor was apparently thinking about the factors of 850 itself, not numbers that would have 850 as their greatest common factor.

There is neither a greatest common factor nor common factors of a single number, such as 10, 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 10 are 1, 2, 5, and 10. The prime factors of 10 are 2 and 5. Examples: The common factors of 10 and 35 are 1 and 5; the greatest common factor is 5. The common factors of 10 and 38 are 1 and 2; the greatest common factor is 2. The common factors of 10 and 90 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 10 and 108 are 1 and 2; the greatest common factor is 2.
