Question

select all the expressions which have 3 as the greatest common factor of the terms.\\(\square\\) \\(b + 3 + 6c\\)\\(\square\\) \\(27n + 66p\\)\\(\square\\) \\(38 - 9j + 6k\\)\\(\square\\) \\(12x + 75y + 21\\)\\(\square\\) \\(-32 - 24z\\)

Explanation:

Step1: Find GCF of terms 1

Terms: $b, 3, 6c$. GCF of $1, 3, 6$ is $1$.

Step2: Find GCF of terms 2

Terms: $27n, 66p$. GCF of $27, 66$ is $3$.

Step3: Find GCF of terms 3

Terms: $38, -9j, 6k$. GCF of $38, 9, 6$ is $1$.

Step4: Find GCF of terms 4

Terms: $12x, 75y, 21$. GCF of $12, 75, 21$ is $3$.

Step5: Find GCF of terms 5

Terms: $-32, -24z$. GCF of $32, 24$ is $8$.

Answer:

$\boldsymbol{27n + 66p}$, $\boldsymbol{12x + 75y + 21}$
