Find the GCF of 45G +30 H

To find the greatest common factor (GCF) of 45G and 30H, we need to determine the factors that both terms have in common.

The factors of 45G are: 1, 3, 5, 9, 15, 45
The factors of 30H are: 1, 2, 3, 5, 6, 10, 15, 30

The common factors are: 1, 3, 5, 15

Therefore, the greatest common factor (GCF) of 45G and 30H is 15.
