Find the GCF of 15 q + 6.

The given expression, 15q + 6, cannot be simplified or factored further. Therefore, the greatest common factor (GCF) of 15q + 6 is 1.

Wrong

Apologies for the incorrect response. To find the greatest common factor (GCF) of 15q + 6, we need to factor out the expression.

By factoring out the GCF, we get:

15q + 6 = 3(5q + 2)

The factorization of 15q + 6 is 3(5q + 2). Therefore, the GCF of 15q + 6 is 3.

Find the GCF of 8d -20

To find the GCF of 8d - 20, we can factor both terms.

The factors of 8d are 1, 2, 4, 8, d, 2d, 4d, and 8d.
The factors of 20 are 1, 2, 4, 5, 10, and 20.

The common factors of 8d and 20 are 1, 2, and 4.

Therefore, the GCF of 8d - 20 is 4.

Find the GCF of 45g+30h

To find the GCF of 45g + 30h, we can factor out the common factors in both terms.

The factors of 45g are 1, 3, 5, 9, 15, 45, g, 3g, 5g, 9g, 15g, 45g.
The factors of 30h are 1, 2, 3, 5, 6, 10, 15, 30, h, 2h, 3h, 5h, 6h, 10h, 15h, 30h.

The common factors of 45g and 30h are 1, 3, 5, and 15.

Therefore, the GCF of 45g and 30h is 15.

Factor 9z+18 using the GCF

To factor out the greatest common factor (GCF) of 9z + 18, we need to identify the largest common factor of both terms.

The factors of 9z are 1, 3, 9, z, and 3z.
The factors of 18 are 1, 2, 3, 6, 9, 18.

The largest common factor of 9z and 18 is 9.

Now we can factor out the GCF from each term:

9z + 18 = 9(z + 2)

Therefore, we have factored 9z + 18 to 9(z + 2).
