>>Firstly, on a home console there are just two playable frame rates: 30 fps and 60 fps.
This is probably very basic but I am going to ask anyway: why are 40fps, 45fps or 47fps not possible?

Over a second, it's of course entirely possible to get something in-between, where some frames are displayed for 1 refresh, and others for 2 refreshes. Inconsistently waffling between these is going to be more jarring than sticking to one.
Recently, you have things like nVidia's... gsync? Which make the monitor refresh rate variable with compatible monitors, to match the game framerate, making 45fps entirely possible, and reducing the jarring from varying frame lengths. But this recent, rare, and likely PC and/or GPU vendor specific still.
Thi sisn't strictly true any more, since many TVs now support 72 Hz (to be able to display 24 fps content like film), but my guess is that doesn't have wide enough support to rely on.
