Basically you need the LCM of the numbers...
10 and 2... 2 goes evenly into 10, so it's 10
Then you need to deal with each variable..
you need w^8 at least, x^7, and z
(because with variables raised to powers, you need to keep at least the highest power... anything with the same base and less power will work)
so the LCM is 10w^8x^7z
To check you are correct, try to multiply your original expressions by something to get the LCM that you found.
10w^8 x^7z (1) = 10w^8 x^7z
and 2w^3z (5w^5x^7) = 10w^8 x^7z
(others are mistaken,,, you don't need w^24 at all!)
