115 has a square sum of divisors: [1] σ ( 115 ) = 1 + 5 + 23 + 115 = 144 = 12 2 . {\displaystyle \sigma (115)=1+5+23+115=144=12^{2}.} There are 115 different rooted trees with exactly eight nodes, [ 2 ] 115 inequivalent ways of placing six rooks on a 6 × 6 chess board in such a way that no two of the rooks attack each other, [ 3 ] and 115 ...
The smallest base greater than binary such that no three-digit narcissistic number exists. 80: Octogesimal: Used as a sub-base in Supyire. 85: Ascii85 encoding. This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 ...
Quaternary numeral system (base 4) Quater-imaginary base (base 2 √ −1) Quinary numeral system (base 5) Pentadic numerals – Runic notation for presenting numbers; Senary numeral system (base 6) Septenary numeral system (base 7) Octal numeral system (base 8) Nonary (novenary) numeral system (base 9) Decimal (denary) numeral system (base 10)
In general, if b is the base, one writes a number in the numeral system of base b by expressing it in the form a n b n + a n − 1 b n − 1 + a n − 2 b n − 2 + ... + a 0 b 0 and writing the enumerated digits a n a n − 1 a n − 2... a 0 in descending order. The digits are natural numbers between 0 and b − 1, inclusive.
In books and articles, when using initially the written abbreviations of number bases, the base is not subsequently printed: it is assumed that binary 1111011 is the same as 1111011 2. The base b may also be indicated by the phrase "base-b". So binary numbers are "base-2"; octal numbers are "base-8"; decimal numbers are "base-10"; and so on.
The only base-4 repunit prime is 5 (). = (+) (), and 3 always divides + when n is odd and when n is even. For n greater than 2, both + and are greater than 3, so removing the factor of 3 still leaves two factors greater than 1.
