What are the common factors and greatest common factor of 80?

Short answer: There are none.There is neither a greatest common factor nor common factors of a single number, such as 80, 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 14 and 80 are 1 and 2; the greatest common factor is 2.The common factors of 32 and 80 are 1, 2, 4, 8, and 16; the greatest common factor is 16.The common factors of 60 and 80 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.The common factors of 70 and 80 are 1, 2, 5, and 10; the greatest common factor is 10.The common factors of 80 and 102 are 1 and 2; the greatest common factor is 2.The factors of 80 are 1,2,4,5,8,10,16,20,40 and 80. For them to have something in common, you need another set of factors to compare them to.
