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 ...
The lowest common denominator of a set of fractions is the lowest number that is a multiple of all the denominators: their lowest common multiple. The product of the denominators is always a common denominator, as in: + = + =

m and n are coprime (also called relatively prime) if gcd(m, n) = 1 (meaning they have no common prime factor). 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 ...
The supremum of a subset of (,) where denotes "divides", is the lowest common multiple of the elements of . The supremum of a set S {\displaystyle S} containing subsets of some set X {\displaystyle X} is the union of the subsets when considering the partially ordered set ( P ( X ) , ⊆ ) {\displaystyle (P(X),\subseteq )} , where P ...
It is the lowest common multiple of the HDTV resolutions. 3840 × 2160 was chosen as the resolution of the UHDTV1 format defined in SMPTE ST 2036-1, [39] as well as the 4K UHDTV system defined in ITU-R BT.2020 [40] [41] and the UHD-1 broadcast standard from DVB. [42]
In this tree, the lowest common ancestor of the nodes x and y is marked in dark green. Other common ancestors are shown in light green. In graph theory and computer science, the lowest common ancestor (LCA) (also called least common ancestor) of two nodes v and w in a tree or directed acyclic graph (DAG) T is the lowest (i.e. deepest) node that has both v and w as descendants, where we define ...
