262 (two hundred [and] sixty-two) is a natural number proceeded by the number 261 and followed by 263. It has the prime factorization 2·131.
Mathematical properties[edit]
There are four divisors of this number, the divisors being 1, 2, 131, and 262 itself, which makes it a semiprime.
It is the sixth meandric number....[1] and the ninth open meandric number[2]
As it cannot be divided into the sum of the proper divisors of any number, it is the 17th untouchable number[3]
As it eventually reaches 1 when replaced by the sum of the square of each digit, it is the 40th 10-happy number[4]
As 262 is 262 backwards, it is a palindrome number[5]
262 was once the lowest number not to have its own Wikipedia page for more than three years since March 2017 when 261 was first created[6], this making it a candidate for the lowest uninteresting Number according to the definition given by Alex Bellos.[7] As of March 2021[update], the smallest natural number without its own Wikipedia page is 264, and the smallest prime number without its own Wikipedia page is 283.
