find the greatest common factor of these two expression 18 u^2 v^5 w^3 and 30 u^7 w^4

What is the biggest number that will go into both 18 and 30? Is it 6?
the greatest common factor for variables with exponents is the variable with the smallest power.
for the u's the gcf would be u^2
for v^5 none because the second expression doesn't have a v.
for the w's can you figure it out?
Now, can you put it all together to find the GCF?
