Triangle \(ABC\), with sides of length \(5\), \(6\), and \(7\), has one vertex on the positive \(x\)-axis, one on the positive \(y\)-axis, and one on the positive \(z\)-axis. Let \(O\) be the origin. Find the volume of tetrahedron \(OABC\). The original answer is in the form \(\sqrt{m}\). Please provide the value of \(m\).

Let's think step by step and output the final answer within \boxed{}.
