* Highly composite number: 12 has more divisors than any positive integer less than it. Its divisors are 1, 2, 3, 4, 6, and 12.
* Abundant number: The sum of its proper divisors (divisors excluding itself) is greater than the number itself (1+2+3+4+6 = 16 > 12).
* Superabundant number: It's a stronger version of abundant; the ratio of the sum of its divisors to itself is higher than for any smaller number.
* Base 12 (duodecimal): Twelve is a common base used in counting systems throughout history, possibly due to its high number of divisors.
* Dozen: A group of twelve is called a dozen, and 12 dozen (144) is called a gross. These are still used in some contexts (eggs, pencils, etc.).
* Time: There are 12 hours on a clock face (twice, making 24 hours in a day).
* Astrology: The Zodiac has 12 signs.
* Geometry: A regular dodecagon is a polygon with twelve sides.
These are just a few of the interesting facts related to the number 12. Its significance across various cultures and mathematical properties make it a fascinating number.
