1 and 3
Common factors of 9, 15, and 30 are: 1 and 3.
Common factors of 9 and 15 are: 1 and 3.
The common factors of 9, 12, and 15 are 1 and 3. The GCF is 3.
Factors of 8 = 1,2,4,8 Factors of 15 = 1,3,5,15 The highest common factor is 1

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.
factors: 9: 1,3,9 15: 1,3,5,15 common afctors: 1,3 greatest common factor: 3
Factors of 9 include 1, 3, and 9. Factors of 15 include 1, 3, 5, and 15. Factors common to both 9 and 15 are 1 and 3.
Since 15 is a factor of 45, its factors are the common factors of 15 and 45. The factors of 15 are 1, 3, 5, and 15. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors they have in common are 1, 3, 5, and 15.
The answer is 1 and 3.
