Pythagorean Theorem: A^2 + B^2 = C^2
<span>We know A and C, let's find B by doing it backwards </span>
<span>C^2 - A^2 = B^2 </span>
<span>4^2 - 7 (square root of 7 squared is just 7) = B^2 </span>
<span>16 - 7 = B^2 </span>
<span>9 = B^2 </span>
147 = 3 * 7 * 7
245 = 5 * 7 * 7
so the gcf is 7*7 = 49
abd gcf of y^3 and y^2 is y^2
answer:- 49y^2
