Answer:
8(5x + 3y -7)
Explanation:
A common number in 40x+24y-56 is 8.
40x / 8 = 5x
24y / 8 = 3y
-56 / 8 = -7
We finally get 8 (5x + 3y -7)
Hope this helps!

8 (5x +3y -7)
40x+24y-56
40x = 8*5*x = 2*2*2 *5*x
24y = 3*8*y = 3*2*2*2*y
56 = 7*8 = 7 * 2*2*2
As we can see, each of these terms has a greatest common factor of 8, so we can factor it out
