Melissa says the GCF of 8x2y + 4xy is 4. Adam says the GCF is 4y. Erica says the GCF is 4xy. Who is correct? In complete sentenc
Delvig [45]

Answer:

Erica

Step-by-step explanation:

The given expression is 8x^2y+4xy.

The prime factorization of the first term is

8x^2y=2^3\cdot x^2\cdot y

The prime factorization of the second term is

4xy=2^2\cdot x\cdot y

The greatest common factor is product of the least powers of the common factors.

GCF=2^2\cdot x\cdot y=4xy

Therefore Erica  is correct.
