1 + 3 = 4
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.
To find the common factors of 9 and 18, we first need to list the factors of each number. The factors of 9 are 1, 3, and 9, while the factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 9 and 18 are 1, 3, and 9. Adding these common factors together gives us a sum of 13.
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.
