1 and 3
The common factors are: 1, 3.
The GCF of 9 and 42 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42. 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 42 are 2, 3, and 7. The prime factors in common are a single 3, so the greatest common factor is 3.

The common factors of 18 and 42 are 1, 2, 3, and 6. The factors of 18 are 1, 2, 3, 6, 9, and 18. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors of 18 and 42 are 1, 2, 3, and 6.
The greatest common factor (GCF) is 3.
The factors of 18 are: 1, 2, 3, 6, 9, 18.The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.The common factors are: 1, 2, 3, 6.The Greatest Common Factor (GCF) is: 6
The common factors of 42 and 273 are 1, 3, 7 and 21.
The GCF of 9, 18, and 42 is 3.The factors of 9 = 3*3The factors of 18 = 2*3*3The factors of 42 = 2*3*7So the greatest common factor = 3.
The common factors of 22 and 42 are: 1 and 2
The common factors of 42 and 77 are: 1 and 7
The common factors of 42 and 92 are: 1 and 2
