Is the following expression shown the exact answer? 144π - 216√3<br><br> true or false

Vsevolod [243]

$144\pi - 216\sqrt{3} \\\\
144 = 2^4 \times 3^2\\\\
216 = 2^3 \times 3^3\\\\
\Longrightarrow~~\text{Common factor } = 2^3 \times 3^2 = 8 \times 9 = 72\\\\
\Longrightarrow~~
144\pi - 216\sqrt{3} = \boxed{72\Big(2\pi - 3\sqrt{3} \Big)}$
