In mathematics
244 is:
- the sum of two nonzero fifth powers (244 = 1 + 243 = 15 + 35).[1]
- palindromic in bases 3 (1000013), 11 (20211), 60 (4460), 121 (22121), 243 (11243).
- a Harshad number in bases 3, 9, 11, 61, 62, 81, 121, 122, 123, 184, 241 and 243.
- the second anti-perfect number, meaning that reversing the digits of the proper divisors of 244 and adding the results gives 244 back again.[2]
- part of the sequence 1, 2, 4, 8, 61, 221, 244, ... in which each number is formed by reversing the digits of the double of the previous number.[3]
