There isn't a universal way of doing that you'll need to know some of the original parameters (e.g. was a Y-axis rotation).
You can extract an x,y,z angles (tilt/yaw/roll) but then you'll still need to know the order of the original angles, and even then you won't get the exact same results just values which give the same matrix.
