Little known fact: 22 is the smallest prime that can be formed from the product of smaller primes in four different ways (7x3, 3x7, and 7x1x3). Anyway, check out the 22nd skeptics circle.

Is this a snare for the unthinking (let's see how widely copied through the net this gets?) or a typo or an unthinking moment?
My grasp of mathematics is fairly rudimentary but surely -
no prime is the product of any other primes except itself and one,
22 is divisable by 11 and 2, thus not a prime,
7x3 equals 21 not 22,
7x3 is the same as 3x7 and 7x3x1 not different amd represents one way to get ...21 and zero ways to get 22.
ok... so space is a spiral, and time is a curve. Have I got that right?
Ken,
You forgot to mention that Tim says "four" ways and then only lists 3. Without going out too far on a limb here, I think we can say this is a joke.
Nope :-) but try any of these:
