Answer:

#2a^2#

Explanation:

You first factorize both expressions:
#16a^2=2*2*2*2*a*a#
#30a^2=2*3*5*a*a#

If you take the common factors, you will see that the GCF will be:
#2*a*a=2a^2#

Of course, in this case it could have been done faster, but the way I described the steps will work in all cases.
