\[
16a^{2}b^{2} - 4a^{2}c^{2} - 16b^{2}d^{2} + 4c^{2}d^{2}
\]
\(4\left (a - d\right )\left (a + d\right )\left (2b + c\right )\left (2b - c\right )\)
\(4\left (a + b\right )^{2}\left (2b + c\right )^{2}\)
\(4\left (a - b\right )\left (a + b\right )\left (2b + c\right )\left (2b - c\right )\)
\(4\left (a - c\right )\left (a + c\right )\left (2b + d\right )\left (2b - d\right )\)
