Micro Four Thirds lenses and magnification factors

Can someone please explain to me how to convert the focal lengths of Micro Four Thirds lenses into magnification factors? Theoretically, I know we divide the bigger focal length by the smaller one, so the 14-42 mm lens has a magnification factor of 3X... but then the 45-200 mm has a magnification factor of only 4.4X... I do understand the difference at the smaller end, meaning that the 14-42mm lens can focus on nearer objects (macro) more than the 45-200 mm lens... but I just cant grasp how the opposite works, cause I am sure it isn't only a matter of focus, but of magnification as well.
I am just too confused, I guess... and my physics is really bad
Would appreciate your help.
