With its successor ( 3 ) it forms an eRAP , since the sums of their prime factors are consecutive (2 and 3 ). 2 is an odious number , because the sum of its binary digits is odd. The product of its digits is 2 , while the sum is 2 . The square root of 2 is about 1.4142135624. The cubic root of 2 is about 1.2599210499. The spelling of 2 in words is "two", and thus it is an aban number , an eban number , an iban number , and an uban number . It is the 2-nd Perrin number . It is a Curzon number .

It is a partition number , being equal to the number of ways a set of 2 identical objects can be partitioned into subset. It is a nialpdrome in base 2. It is a self number , because there is not a number n which added to its sum of digits gives 2. It is a panconsummate number . 2 is an untouchable number , because it is not equal to the sum of proper divisors of any number. It is a subfactorial , being equal to the number of derangements of 3 objects . It is a good prime . It is a Pierpont prime , being equal to 2 0 ⋅ 3 0 + 1. It is an impolite number , since it cannot be written as a nontrivial sum of consecutive naturals. It is a (trivial) narcissistic number . 2 is a highly composite number , because it has more divisors than any smaller number. 2 is a superabundant number , because it has a larger abundancy index than any smaller number.
