2013

Welcome to the new year! As usual, here’s some trivia about the number 2013.

2013 starts a sequence of years with interesting factorizations — factorizations with all primes less than 100. These are numbers for which it is easy to write interesting problems, and the next few years should give plenty of those.

2013 = 3 \times 11 \times 61
2014 = 2 \times 19 \times 53
2015 = 5 \times 13 \times 31
2016 = 2^5 \times 3^2 \times 7

In other news, 2013 is the first year since 1987 consisting of four distinct digits. It’s also the first new year we’ve entered since a whole year ago… and that’s a cause for celebration, and possibly alarm and concern.
