## 2012: Happy New Number!

Welcome 2012! It will be hard to measure up to the numerous numerical nuances of 2011, but the number 2012 does possess some interesting properties.

The prime factorization of 2012 is noteworthy:

Not only does 2012 have only two distinct prime factors, but the prime factor 503 is rather large. In fact, 2012 is an unusual number, in that its largest prime factor is greater than its square root.

Also, since 2012 has exactly three prime factors, it is considered triprime (or **3-semiprime**).

We might not enjoy as many special numerical days this year (like palindrome days or permutation days), but I do look forward to writing 2012 for the next 365 days!

*366 days since 2012 is divisible by 2^2, but not 100 (unless divisible by 400 too).

🙂

Although its possible that there is one day in this year on which you *don’t* look forward to writing 2012, and if so I apologize for this comment.

So, for my first post of the new year, in which I describe some interesting things about 2012, I completely miss one of the most obviously interesting things about it?

This could be a long 366 days.

Also, its Alan turing year and National Mathematical Year of India (as a tribute to S. Ramanujan)

But 2011 was unique number http://we-luv-math.blogspot.com/2011/11/something-unique-about-year-2011.html

Paraphrasing from the WolframAlpha link: the probability that a number is unusual is ln(2). Talk about confusing interpretations of probability!

Technically, it’s 365 as this post covers the first day of the year. 😉
