If satisfies the ascending chain condition, a subset of has a greatest element if, and only if, it has one maximal element. [ note 5 ] When the restriction of ≤ {\displaystyle \,\leq \,} to S {\displaystyle S} is a total order ( S = { 1 , 2 , 4 } {\displaystyle S=\{1,2,4\}} in the topmost picture is an example), then the notions of maximal ...
If satisfies the ascending chain condition, a subset of has a greatest element if, and only if, it has one maximal element. [ proof 4 ] When the restriction of ≤ {\displaystyle \,\leq \,} to S {\displaystyle S} is a total order ( S = { 1 , 2 , 4 } {\displaystyle S=\{1,2,4\}} in the topmost picture is an example), then the notions of maximal ...
lcm(m, n) (least common multiple of m and n) is the product of all prime factors of m or n (with the largest multiplicity for m or n). gcd(m, n) × lcm(m, n) = m × n. Finding the prime factors is often harder than computing gcd and lcm using other algorithms which do not require known prime factorization.
This is a list of articles about prime numbers.A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem, there are an infinite number of prime numbers.
Then, by the well-ordering principle, there is a least element ; cannot be prime since a prime number itself is considered a length-one product of primes. By the definition of non-prime numbers, n {\displaystyle n} has factors a , b {\displaystyle a,b} , where a , b {\displaystyle a,b} are integers greater than one and less than n ...
Equivalently, any two elements of R have a least common multiple (LCM). [1] A GCD domain generalizes a unique factorization domain (UFD) to a non-Noetherian setting in the following sense: an integral domain is a UFD if and only if it is a GCD domain satisfying the ascending chain condition on principal ideals (and in particular if it is ...

A set with upper bounds and its least upper bound. In mathematics, particularly in order theory, an upper bound or majorant [1] of a subset S of some preordered set (K, ≤) is an element of K that is greater than or equal to every element of S.
