116

116 is the natural number that follows 115 and precedes 117. In mathematics, it is an even composite number with prime factorization 2^2 × 29. Its positive divisors are 1, 2, 4, 29, 58, and 116. The sum of its proper divisors is 94, making 116 a deficient number. In various numeral systems, 116 is written as 1110100 in binary, 0x74 in hexadecimal, and 164 in octal. In Roman numerals it is CXVI. The decimal value 116 also corresponds to the ASCII code for the lowercase letter 't'.

In science, 116 is the atomic number of livermorium, a synthetic superheavy element. Livermorium is placed in group 16 (the chalcogens) and in the seventh period of the periodic table. All known isotopes of livermorium are highly unstable and decay within milliseconds to seconds. Livermorium was first synthesized in 1999–2000 by collaborations at the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory in the United States, using the fusion reaction of curium-248 with calcium-48. The element is named in honor of Lawrence Livermore National Laboratory. In practice, livermorium is studied primarily in experimental nuclear science to explore the properties of superheavy nuclei and to test models of nuclear stability.

Beyond mathematics and chemistry, 116 appears in various coding and labeling systems as a numerical identifier, such as its use as a character code in computing and as part of cataloging schemes.
