# But Wait… Perhaps “Divisible by 7, 11, and 13” Is a Red Herring—But No In an age where numbers often carry hidden meanings, cryptic clues appear everywhere—especially in puzzles, riddles, and viral internet lore. One such enigmatic phrase is “divisible by 7, 11, and 13”—a simple mathematical claim that, at first glance, feels like a routine divisibility test. But what if it’s more than just a math fact? What if it’s a deliberate red herring—an intentional misdirection built to provoke curiosity and deeper thinking? ### The Surface Claim: Divisible by 7, 11, and 13 On its most basic level, the statement “divisible by 7, 11, and 13” is straightforward: it refers to a number that shares all three prime factors. Clearly, any multiple of the least common multiple (LCM) of 7, 11, and 13—217 with LCM(7,11,13) = 1001—is divisible by each number. So logically, the phrase does not convey special significance beyond elementary number theory.
