What are the common factors and greatest common factor of 75?

There is neither a greatest common factor nor common factors of a single number, such as 75, 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 75 are 1, 3, 5, 15, 25, and 75. The common factors of 50 and 75 are 1, 5 and 25; the greatest common factor is 25. The common factors of 75 and 90 are 1, 3, 5, and 15; the greatest common factor is 15. The common factors of 10 and 75 are 1 and 5; the greatest common factor is 5.
