Example: 30 and 42

1, 2, 3, 5, 6, 10, 15, 30

1, 2, 3, 6, 7, 14, 21, 42

These are the factors of 30 and 42. The numbers that appear on both lists are common factors. Of those, the largest one (indicated in bold) is the GCF.

The Greatest Common Factor (GCF) is: 8

The greatest common factor is 2

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.

The greatest common factor of 30 and 39 is 3.

The greatest common factor (GCF) is: 5.

If you consider the numbers 2,4,6 and 8, the greatest common factor is 2.

24 is not the greatest common factor of any single number. Common factors are the factors that two or more numbers have in common. The greatest common factor is the largest factor that two or more numbers have in common. There cannot be any common factors or a greatest common factor of a single number. There must be at least two number for common factors and a greatest common factor. Example: The greatest common factor of 24 and 48 is 24. The greatest common factor of 60 and 144 is 24. The greatest common factor of 240 and 264 is 24.

The greatest common factor of 6 and 9 is not 5.

Yes, the greatest common factor is less than or equal to the smallest coefficient. For example, the greatest common factor of 38 and 8 is 2.

An infinite number of number pairs have a greatest common factor of 850. One example is 1700 and 2550.

The greatest factor that two or more numbers have in common is known as the greatest common factor, or GCF.

The GCF of 30 and 42 is 6.

A greatest common factor is the largest factor between two or more numbers. For example, the greatest common factor of 10 and 12 is 2. Because the factors of 10 are 1,2,5, and 10 and the factors of 12 are 1,2,3,4,6, and 12. Since 2 is the largest factor that they both share, it is the greatest common factor.

The greatest common factor, or GCF, is the largest positive integer that will divide evenly with no remainder into all the members of a given set of numbers.

Greatest common factor applies to a set of two numbers. For example, the greatest common factor of 16 and 24 is 8, since it is the largest number that goes into both.

There is no common factor for a single number. The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.
