Can the greatest common factor be greater than 18?

The Greatest Common Factor depends upon the numbers for which there are common factors and it is the greatest one of them; it can be greater than 18, for example the greatest common factor of 40 and 100 is 20. The greatest common factor must be one of the factors of each of the numbers. As the factors of each number cannot be greater than that number, the greatest common factor of a set of numbers cannot be greater than the least number. If this number is not greater than 18 then the greatest common factor of the numbers cannot be greater than 18. Even if the least number is greater than 18 it is possible that the greatest common factor of a set of numbers is still not greater than 18, for example the greatest common factor of 20, 30 and 50 is 10.

What are the common factors and greatest common factor of 20?

There is neither a greatest common factor nor common factors of a single number, such as 20, 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 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2, 2, and 5. Examples: The common factors of 20 and 70 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 20 and 32 are 1, 2, and 4; the greatest common factor is 4. The common factors of 20 and 140 are 1, 2, 4, 5, 10, and 20; the greatest common factor is 20.

How are factors common factors and greatest common factors different?

A factor of a number is a number that number can be divided by. For instance, 20 has the factors 1, 2, 4, 5, 10 and 20. 28 has the factors 1, 2, 4, 7, 14 and 28. Common factors are factors which appear in both lists. In this instance, 1, 2 and 4 are common factors of 20 and 28. The greatest common factor is the biggest number out of the common factors. In this case, 4 is the greatest common factor.
