Answer:
5xy
Step-by-step explanation:
I'm going out on a limb and assuming exponents.

We can note that 5 is a common factor for the coefficients. All the terms share at least one x. All the terms share all least one y. So the GCF of these monomials is 5xy.
Step-by-step explanation:
(root under) 2×3×3×4
(root under) 2×3×3×2×2
3×2 (root under) 2
6 (root under) 2
sorry i don't have the root under symbol, if you are confused it is the symbol that is at the first of your question.
