I do not believe this is possible. Here's why.

The factors of 72 are

36*2

18*4

12*6

9*8

Now to get a positive 72 both the factors must be negative so let's just add all the possible factors and see if we can come up with -19

-36 + (-2) = -38

-18 + (-4) = -22

-12 + (-6) = -18

-9 + (-8) = -17

So there you have it... no -19. I hope this is right!
