114 (one hundred [and] fourteen) is the natural number following 113 and preceding 115.

In mathematics

  • 114 is an abundant number, a sphenic number[1] and a Harshad number.[2] It is the sum of the first four hyperfactorials, including H(0). At 114, the Mertens function sets a new low of -6, a record that stands until 197.
  • 114 is the smallest positive integer* which has yet to be represented as a³ + b³ + c³, where a, b, and c are integers. It is conjectured that 114 can be represented this way. (*Excluding integers of the form 9k ± 4, for which solutions are known not to exist.)[3]
  • There is no answer to the equation φ(x) = 114, making 114 a nontotient.[4]
  • 114 appears in the Padovan sequence,[5] preceded by the terms 49, 65, 86 (it is the sum of the first two of these).
  • 114 is a repdigit in base 7 (222).
