  2. Least common multiple - Wikipedia

    en.wikipedia.org/wiki/Least_common_multiple

    The least common multiple of the denominators of two fractions is the "lowest common denominator" (lcd), and can be used for adding, subtracting or comparing the fractions. The least common multiple of more than two integers a , b , c , . . . , usually denoted by lcm( a , b , c , . . .) , is defined as the smallest positive integer that is ...

    en.wikipedia.org/wiki/Linear_congruential_generator

    The generator is not sensitive to the choice of c, as long as it is relatively prime to the modulus (e.g. if m is a power of 2, then c must be odd), so the value c=1 is commonly chosen. The sequence produced by other choices of c can be written as a simple function of the sequence when c=1.

    en.wikipedia.org/wiki/C_mathematical_functions

    The functions that operate on integers, such as abs, labs, div, and ldiv, are instead defined in the <stdlib.h> header (<cstdlib> header in C++). Any functions that operate on angles use radians as the unit of angle. [1] Not all of these functions are available in the C89 version of the standard. For those that are, the functions accept only ...

  6. Landau's function - Wikipedia

    en.wikipedia.org/wiki/Landau's_function

    In mathematics, Landau's function g(n), named after Edmund Landau, is defined for every natural number n to be the largest order of an element of the symmetric group S n. 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 ...

  8. Carmichael function - Wikipedia

    en.wikipedia.org/wiki/Carmichael_function

    The Carmichael lambda function of a prime power can be expressed in terms of the Euler totient. Any number that is not 1 or a prime power can be written uniquely as the product of distinct prime powers, in which case λ of the product is the least common multiple of the λ of the prime power factors.

  9. Euclidean algorithm - Wikipedia

    en.wikipedia.org/wiki/Euclidean_algorithm

    In the second step, any natural number c that divides both a and b (in other words, any common divisor of a and b) divides the remainders r k. By definition, a and b can be written as multiples of c: a = mc and b = nc, where m and n are natural numbers. Therefore, c divides the initial remainder r 0, since r 0 = a − q 0 b = mc − q 0 nc = (m ...
