For example, 10 is a multiple of 5 because 5 × 2 = 10, so 10 is divisible by 5 and 2. Because 10 is the smallest positive integer that is divisible by both 5 and 2, it is the least common multiple of 5 and 2. By the same principle, 10 is the least common multiple of −5 and −2 as well.
The set of numbers less than and coprime to 5 is {1,2,3,4}. Hence Euler's totient function has value φ (5) = 4 and the value of Carmichael's function, λ (5) , must be a divisor of 4. The divisor 1 does not satisfy the definition of Carmichael's function since a 1 ≢ 1 ( mod 5 ) {\displaystyle a^{1}\not \equiv 1{\pmod {5}}} except for a ≡ 1 ...

[1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).
For example, a modulus of F 5 = 2 32 + 1 might seem attractive, as the outputs can be easily mapped to a 32-bit word 0 ≤ X i − 1 < 2 32. However, a seed of X 0 = 6700417 (which divides 2 32 + 1) or any multiple would lead to an output with a period of only 640.
Tcl: As of version 8.5 (2007), integers are arbitrary-precision by default. (Behind the scenes, the language switches to using an arbitrary-precision internal representation for integers too large to fit in a machine word. Bindings from C should use library functions such as Tcl_GetLongFromObj to get values as C-native data types from Tcl ...
Rosetta Code is a wiki-based programming chrestomathy website with implementations of common algorithms and solutions to various programming problems in many different programming languages. [ 1 ] [ 2 ] It is named for the Rosetta Stone , which has the same text inscribed on it in three languages, and thus allowed Egyptian hieroglyphs to be ...
The greatest common divisor (GCD) of integers a and b, at least one of which is nonzero, is the greatest positive integer d such that d is a divisor of both a and b; that is, there are integers e and f such that a = de and b = df, and d is the largest such integer.
