The ∤ (does not divide) symbol is a mathematical operator used in number theory to indicate that one integer cannot be evenly divided by another without leaving a remainder. Visually represented as a vertical line with a diagonal slash through it, it acts as the direct negation of the standard "divides" (|) symbol. While primarily found in academic texts and math proofs, it also appears in technical documentation to represent indivisibility.
