Question

Factor the expression using the GCF. 18h + 30K

Answer 1

Answer: 6(3h + 5k)

We are given 18 h + 30k

Firstly, we need to find the prime factor of each figure

`\begin{gathered} \text{Prime factor of 18 = 2 x 3 x 3} \\ \text{Prime factor of 30 = 2 x 3 x 5} \\ \text{Hence, the GCF = 2 x 3 } \\ \text{GCF = 6} \\ \text{Hence, the expression can be written as} \\ 6(3h\text{ + 5k)} \end{gathered}`
