How cool is the number 12

I always liked numbers and I think one of the coolest is the number 12. Why is 12 cool? Well for one, it's used for clocks. And what's neat is that 12 is evenly divisible by 2,3,4 and 6. So it's one of these highly abundant numbers. It's actually a superabundant number.

I don't know what all that means, but I'm sure if I mention it I'll look smart and that I know what I'm talking about.

Other superabundant numbers are 1, 2, 4, 6, 12, 24, 36, 48, 60, 120, 180, 240, 360, 720, 840, 1260, 1680, 2520, 5040, 10080, 15120, 25200, 27720, 55440, 110880, 166320, 277200, 332640, 554400, 665280, 720720, 1441440, 2162160, 3603600, 4324320, 7207200, 8648640, 10810800, 21621600.

There's actually a catalog of number sequences where this is listed as http://oeis.org/A004394

And our good friends 24, 60 and 360 show up here. 24 is used for hours in a day, 60 for minutes in an hour and 360 is used for degree measure (and is really close to the number of days in a year). 12 is also the number of months in a year. And the number of inches in a foot.

This post is brought to you by the letters A,B and the number 12.
