4 and 9 share no common factors aside from 1.
4 = 2 x 2
9 = 3 x 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 are 1 and 3.
The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36The factors of 81 are: 1, 3, 9, 27, 81The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
The common factors of 16 and 36 are 1, 2 and 4. factors of 16 are 1, 2, 4, 8, 16 Factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, 36 So common factors are 1, 2 and 4
The factors of 81 are 1, 3, 9, 27, and 81. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The common factors of 81 and 36 are 1, 3, and 9.
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.
No, because 4 and 9 have no factors in common.
The factors of 8 are 1, 2, 4, and 8, and the factors of 9 are 1, 3, 9 so the 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 common factors are 1 and 3.
2, 3, 4 and 9 have only one common factor: 1
The factors of 27 are: 1, 3, 9, 27The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36The common factors are: 1, 3, 9
The factors of 16 are 2, 4 and 8. The factors of 36 are 2, 4, 9, 12 and 18. The common factors are therefore 2 and 4. The common prime factor is 2.
The factors of 9 are: 1, 3, 9The factors of 68 are: 1, 2, 4, 17, 34, 68The common factors are: 1The Greatest Common Factor (GCF) is: 1
Just 1.
The factors of 36 are:1, 2, 3, 4, 6, 9, 12, 18, 36The factors of 45 are:1, 3, 5, 9, 15, 45The common factors are: 1, 3, 9
The factors of 9 are 1, 3, 9 The factors of 16 are 1, 2, 4, 8, 16 The common factor of 9 and 16 is 1
3, 4, and 7 are the common factors of 9 12 and 21.
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.
