The GCF of 24, 32, and 80 must be 8, since it is the largest number common to both lists. Example 1 Find the greatest common factor of each set of numbers by listing factors.
        
             
        
        
        
Answer:   M = -20w + 450

Hi there.
I'm just going to put the answer for now. I might come back and edit my answer if I figure out how to solve this the long way.
All I did was figure out what exponent you raise 10 to. 
10³ = 1000
So, we now have 8 + 10³ = 1008
Edit:
I did it on paper - here it is broken down.
8 + 

 = 1008
Subtract 8 from both sides.

 = 1000
We know that 10³ = 1000
<em>x</em> = 3
