To find the greatest common factor (GCF) of the expression \(45g + 30h\), we need to factor out any common factors from the coefficients of the terms.
-
Identify the coefficients: The coefficients in the expression are 45 and 30.
-
Find the GCF of the coefficients:
- The factors of 45 are: \(1, 3, 5, 9, 15, 45\)
- The factors of 30 are: \(1, 2, 3, 5, 6, 10, 15, 30\)
- The common factors are: \(1, 3, 5, 15\)
- The greatest common factor is \(15\).
-
Factor out the GCF: Now we can factor the GCF out of the original expression: \[ 45g + 30h = 15(3g + 2h) \]
So, the GCF of \(45g + 30h\) is \(15\), and the expression can be rewritten as: \[ 15(3g + 2h) \]
