In theory Magenta, Cyan and Yellow should give you Black. In practical terms it will give you a fairly desatured gray, almost close to black - if you're lucky. Pigments aren't an exact science, and most manufacturers have different palettes of primary colors. To make things worse every brand is sub-divided into different qualities from the most economic to the most expensive.
So the problem of making gray in such a fashion is in choosing the right pigments, hues, brand and manufacturer.
I've found that even though the RGB system (we were talking CMYK before) is meant to be additive (ie: applied to light and not pigment), you can obtain almost ivory black by mixing vermillion with cobalt blue (ultramarine works better but is not the correct one) and viridian green (windsor & newton's galeria or finity).
But that's an experiment i did long ago, I'm not sure if the quantities of each paint were in exact proportion or even if i cheated a bit by adding other colors...
With CMYK, i'd suggest medium cadmium yellow, permanent magenta (the closest brand you find to burgandy, keeping an eye out to avoid any blue mixed in) and cyan or cerulean (be careful to not get one wich could have any white in it). Mix equal portions of magenta and cyan and add yellow until it desaturates all the violet shade. Test the hue with white on the side. Also avoid trusting your eyes on this, everyone will have a different impression of the color. To make it easy get a black or dark grey paper to match against your results as you mix the colors.
It's a very good question, one that every painter interested in color theory should try to explore at least once. But routinely mixing gray by such process would be unthinkable, since there's plenty other easier alternatives. And you have no control over the luminosity of the gray with this technique unless you then add white, wich kind of defeats the purpose.
