• 108 can be written using four 4's:
108 is nontrivially palindromic in base 11.
108 is digitally balanced in base 4, because in such base it contains all the possibile digits an equal number of times.
It is a tau number, because it is divible by the number of its divisors (12).
It is a tetranacci number.
108 is strictly pandigital in base 4.
108 is a nontrivial repdigit in base 11.
It is a plaindrome in base 11, base 14 and base 16.
It is a nialpdrome in base 3, base 6, base 11, base 12, base 13 and base 15.
It is a zygodrome in base 3 and base 11.
It is a self number, because there is not a number n which added to its sum of digits gives 108.
108 is a gapful number since it is divisible by the number (18) formed by its first and last digit.
It is an amenable number.
It is a pseudoperfect number, because it is the sum of a subset of its proper divisors.
108 is a wasteful number, since it uses less digits than its factorization.
108 is an evil number, because the sum of its binary digits is even.
The square root of 108 is about 10.3923048454. The cubic root of 108 is about 4.7622031559.
Adding to 108 its reverse (801), we get a palindrome (909).
The spelling of 108 in words is "one hundred eight", and thus it is an aban number.
