U+2224 "∤" Does Not Divide Unicode Character
Unicode Version 17.0
∤
U+2224 "∤" Does Not Divide is a mathematical symbol primarily used in number theory and logic to denote that one integer does not divide another, serving as the negation of the standard vertical bar "|" which indicates divisibility. For example, it is written as "a ∤ b" to mean "a does not divide b," implying that there is no integer k such that b equals a times k, often leaving a non-zero remainder. This symbol helps express concepts like coprime relationships or excluded divisors in formal proofs, equations, and set theory, providing a clear and concise notation for stating a false divisibility condition.
