Find the GCF of 45g+30h .

To find the greatest common factor (GCF) of 45g and 30h, we can start by factoring both terms.

For 45g, we can break it down into 5 * 9 * g, where 5 is prime, 9 is a multiple of 3 multiplied by 3, and g is a variable.

For 30h, we can break it down into 2 * 3 * 5 * h, where 2, 3, and 5 are primes, and h is a variable.

To find the GCF of 45g and 30h, we take the common prime factors of both terms, which are 3 and 5. We multiply these factors together to get the GCF.

Therefore, the GCF of 45g and 30h is 3 * 5 = 15.
