In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
monomials:
12x²y , 28xy², 64y^5
Step 02:
greatest common factor:
12x²y = 2 * 2 * 3 * x * x * y
28xy² = 2 * 2 * 7 * x * y * y
64y^5 = 2 * 2 * 2 * 2 * 2 * 2 * y * y * y * y * y
align the common factors:
2 , 2 , y
find the product of the common factors:
2 * 2 * y = 4y
The answer is:
4y
