Find the GCF of 45g+30h

To find the greatest common factor of 45g and 30h, we need to find the highest number or letter that can divide both terms evenly.

First, let's break down 45g and 30h into their prime factorization.

45g:
- The number 45 can be factored into 3 * 3 * 5.
- The letter g has no other factors.
Therefore, the prime factorization of 45g is 3 * 3 * 5 * g.

30h:
- The number 30 can be factored into 2 * 3 * 5.
- The letter h has no other factors.
Therefore, the prime factorization of 30h is 2 * 3 * 5 * h.

Now, let's find the common factors between the two prime factorizations:

The common factors are 3, 5, and a common letter h.

Therefore, the greatest common factor of 45g and 30h is 3 * 5 * h, which is equal to 15h.

Factor 9z + 18 using the GCF.

To factor 9z + 18 using the GCF, we need to find the largest number or variable that can divide both terms evenly. In this case, the GCF is 9.

So, dividing 9z by 9 gives us z, and dividing 18 by 9 gives us 2.

Therefore, we can factor 9z + 18 as 9(z + 2).
