$G C F = 49 {y}^{2}$

#### Explanation:

Write each term as the product of its prime factors first.

$98 {y}^{3} = 2 \text{ } \times 7 \times 7 \times y \times y \times y$
$245 {y}^{2} = \text{ } \underline{5 \times 7 \times 7 \times y \times y}$

Common factors:$\text{ } 7 \times 7 \times y \times y = 49 {y}^{2}$

The GCF is the product of all the common factors.
