Best Answer

Short answer: There are none.

There is neither a greatest common factor nor common factors of a single number, such as 12, 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 12 are 1, 2, 3, 4, 6, and 12.

Examples:

The common factors of 7 and 12 are only 1; the greatest common factor is 1.

The common factors of 12 and 16 are 1, 2, and 4; the greatest common factor is 4.

The common factors of 12 and 18 are 1, 2, 3, and 6; the greatest common factor is 6.

The common factors of 12 and 30 are 1, 2, 3, and 6; the greatest common factor is 6.

The common factors of 12 and 34 are 1 and 2; the greatest common factor is 2.

The common factors of 12 and 44 are 1, 2, and 4; the greatest common factor is 4.

The common factors of 12 and 96 are 1, 2, 3, 4, 6, and 12; the greatest common factor is 12.

The greatest common factor of the numbers 12, 24 and 48 is 12.The factors of 12 are 1,2,3,4,6,12The factors of 24 are 1,2,3,4,6,8,12,24The factors of 48 are 1,2,3,4,6,8,12,16,24,48so the greatest common factor is 12

The greatest common factor of 9 and 12 is 3. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors are 1 and 3. Therefore, the greatest common factor is 3. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 9 are 3 and 3. The prime factors of 12 are 2, 2, and 3. The prime factors in common are a single 3, so the greatest common factor is 3.

The greatest common factor of 4,12, and 16 is 4.The factors of 4 are 1,2, and 4.The factors of 12 are 1,2,3,4,6, and 12.The factors of 16 are 1,2,4,8, and 16The greatest common factor of 4,12, and 16 is 4.

The greatest common factor of 12 and 25 is 1. One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 25 are 1, 5, and 25. The only common factor is 1. Therefore, the greatest common factor is 1. The numbers are relatively prime. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 12 are 2, 2, and 3. The prime factors of 25 are 5 and 5. There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.

The GCF of 12 and 22 is 2 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 12 are 1, 2, 3, 4, 6, and 12. The factors of 22 are 1, 2, 11, and 22. The common factors are 1 and 2. Therefore, the greatest common factor is 2
