• 180 can be written using four 4's:
180 is nontrivially palindromic in base 14.
180 is digitally balanced in base 2 and base 4, because in such bases it contains all the possibile digits an equal number of times.
180 is an esthetic number in base 5 and base 7, because in such bases its adjacent digits differ by 1.
It is a tau number, because it is divible by the number of its divisors (18).
It is an Ulam number.
180 is strictly pandigital in base 4.
180 is a nontrivial repdigit in base 14.
It is a plaindrome in base 7 and base 14.
It is a nialpdrome in base 6, base 9, base 14, base 15 and base 16.
It is a zygodrome in base 14.
It is a congruent number.
180 is a highly composite number, because it has more divisors than any smaller number.
180 is a superabundant number, because it has a larger abundancy index than any smaller number.
180 is a gapful number since it is divisible by the number (10) 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.
180 is a wasteful number, since it uses less digits than its factorization.
180 is an evil number, because the sum of its binary digits is even.
The square root of 180 is about 13.4164078650. The cubic root of 180 is about 5.6462161733.
Subtracting from 180 its reverse (81), we obtain a palindrome (99).
The spelling of 180 in words is "one hundred eighty", and thus it is an aban number.
