# How do you find the GCF of 5ab, 6b^2?

Mar 6, 2018

See a solution process below:

#### Explanation:

Find the prime factors for each number as:

$5 a b = 5 \times a \times b$

$6 {b}^{2} = 2 \times 3 \times b \times b$

Now identify the common factors and determine the GCF:

$5 a b = 5 \times a \times \textcolor{red}{b}$

$6 {b}^{2} = 2 \times 3 \times \textcolor{red}{b} \times b$

Therefore:

$\text{GCF} = \textcolor{red}{b}$
