Suppose we have a convex polygon in which all interior angles are integers when measured in degrees, and the interior angles at every two consecutive vertices differ by exactly \(1^{\circ}\). If the greatest and least interior angles in the polygon are \(M^{\circ}\) and \(m^{\circ}\), what is the maximum possible value of \(M - m\)?
