Dinner would have been splendid … if the wine had been as cold as the XXXX, the beef as rare as the XXXXXXX, the brandy as old as the XXXX, and the maid as willing as the XXXXXXX.

Attributed to Winston Churchill.

Difficulty: 3 of 5 Bonus: Get it in Gear (in Numbers) Rating: 4.33
Four gears are in constant mesh with each other. Gear A meshes only with Gear B, B meshes with A and C, C meshes with B and D, and D meshes only with C, like this:

A B C D

Gears A, B, C, and D have 35, 27, 84, and 34 teeth, respectively.

If a vertical stripe is painted on each gear, what is the minimum number of revolutions (>0) gear A would have to make before the four stripes are vertical again?
