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 ...

Equivalently, g(n) is the largest least common multiple (lcm) of any partition of n, or the maximum number of times a permutation of n elements can be recursively applied to itself before it returns to its starting sequence. For instance, 5 = 2 + 3 and lcm(2,3) = 6. No other partition of 5 yields a bigger lcm, so g(5) = 6.
For example, the numerators of fractions with common denominators can simply be added, such that + = and that <, since each fraction has the common denominator 12. Without computing a common denominator, it is not obvious as to what 5 12 + 11 18 {\displaystyle {\frac {5}{12}}+{\frac {11}{18}}} equals, or whether 5 12 {\displaystyle {\frac {5 ...
[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).
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 ...
D.Lazard 15:12, 26 July 2021 (UTC) My motivation came from how simple a definition of GCD could be with a simple name for such: "GCD is the product of the members of the intersection of ..." (much simpler still in symbolic form). Also, it could be used in a relatively simple proof that the square root of 2 (et. al) is irrational.
