What is the greatest common factor of 38 and 30?

A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 38 are 1, 2, 19, and 38. The common factors are 1 and 2. Therefore, the greatest common factor is 2.


What are the common factors of 100 and 5030?

Get the greatest common factor first. For example, you might use Euclid's Algorithm - the first step is that the greatest common factor of 5030 and 100 is the same as the greatest common factor of 100 and 30 (where 30 is the remainder of the division of 5030 / 100). Once you get the greatest common factor, the common factors of the two numbers are simply all the factors of this greatest common factor.


What are the greatest common factors of 30 and 16?

30 and 16's highest common factor is two.


What are greatest common factors in 25 and 36?

There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

What are the common factors and greatest common factor of 30?

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 30, 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 30 are 1, 2, 3, 5, 6, 10, 15, and 30. Examples: The common factors of 30 and 32 are 1 and 2; the greatest common factor is 2. The common factors of 30 and 45 are 1, 3, 5, and 15; the greatest common factor is 15. The common factors of 30 and 57 are 1 and 3; the greatest common factor is 3. The common factors of 30 and 65 are 1 and 5; the greatest common factor is 5. The common factors of 30 and 72 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 30 and 100 are 1, 2, 5, and 10; the greatest common factor is 10. The common factors of 30 and 180 are 1, 2, 3, 5, 6, 10, 15, and 30; the greatest common factor is 30.


What is the greatest common factor of 30 and 64?
