$24 + 40 = 8 \times (3 + 5)$ $24+40=8xx(3+5)$

Explanation:

The prime factors of $24$ $24$ are $2 \times 2 \times 2 \times 3$ $2xx2xx2xx3$

and those of $40$ $40$ are $2 \times 2 \times 2 \times 5$ $2xx2xx2xx5$

As $2 \times 2 \times 2 = 8$ $2xx2xx2=8$ is common, GCF is $8$ $8$

and as such $24 + 40$ $24+40$ can be written as

$24 + 40 = 8 \times 3 + 8 \times 5 = 8 \times (3 + 5)$ $24+40=8xx3+8xx5=8xx(3+5)$
