The GCF is 6a.
2 x 3 x 3 x a = 18a
They are 1, 2, 3, 4, 6, 9, 12, 18, 36,1a, 2a, 3a, 4a, 6a, 9a, 12a, 18a, 36a,1b, 2b, 3b, 4b, 6b, 9b, 12b, 18b, 36b,1a2, 2a2, 3a2, 4a2, 6a2, 9a2, 12a2, 18a2, 36a2,1ab, 2ab, 3ab, 4ab, 6ab, 9ab, 12ab, 18ab, 36ab,1b2, 2b2, 3b2, 4b2, 6b2, 9b2, 12b2, 18b2, 36b2.
2 x 3 x 3 x a = 18a
Yes.

18a
That depends on the value of a.
18a^3bc
6a
-16A
The sum of 18 + 30 is 48.
If you mean 3a*3a*2a then it is 18a^3 when simplified
