| For each polynomial, write the factors in the corresponding circle. Since 3 is a factor of A and B only, write 3 where the circles for A and B
overlap.
Since 2, x, and y are factors of A, B, and C, write 2, x, and y in the region
where all three circles overlap.
The common factors lie in the region where all three circles overlap.
The factors in that region are 2, x, and y.
Therefore, the GCF of the polynomials is 2
· x · y = 2xy. |
