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.
Factors of 9 are 1, 3, and 9; factors of 12 are 1, 2, 3, 4, 6, and 12. There are only two common factors of 9 and 12: 1 and 3.
3, 4, and 7 are the common factors of 9 12 and 21.
The common factors of 9, 12, and 15 are 1 and 3. The GCF is 3.
The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 15 are 1, 3, 5, and 15. The common factors of 9, 12, and 15 are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
The GCF of 3, 9, and 12 is 3. Factors of 3 - 1 and 3 Factors of 9 - 1, 3, and 9 Factors of 12 - 1, 2, 3, 4, 6, and 12 The factors that they have in common are 1 and 3. So the GCF, or Greatest Common Factor, is 3.
The factors of 9 are 1, 3, and 9. The factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors of 9 and 12 are 1 and 3.9 ~ 1,3,912 ~ 1,2,3,4,6,12
The common factors are 1 and 3.
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.
