WebIn mathematics, the least-upper-bound property (sometimes called completeness or supremum property or l.u.b. property) [1] is a fundamental property of the real numbers. More generally, a partially ordered set X has the least-upper-bound property if every non-empty subset of X with an upper bound has a least upper bound (supremum) in X.

WebSep 24, 2015 · Explanation: First we define what is Upper Bound of a Set. Any number that is greater than or equal to all of the elements of the set. Hence the least upper bound is.
