Coprime

Every common divisor of a and b is one.

Current library: Alpha v34, 4,223 checked-use theorems; Stable remains 432. Historical first admissions, original proof editions, and non-admitted aliases are preserved. Exact original first-admission records.

Readable signature

Coprime(a, b)

Exact expansion

forall d. (exists x. a = d * x) -> (exists y. b = d * y) -> d = 1

This node is conservative notation, not a theorem, axiom, predicate constant, or kernel rule. Its expansion remains in the unchanged first-order language.

Reviewed Coprime corresponds to blueprint Coprime with checked argument positions [0, 1].

The global atlas describes planning vocabulary and does not itself certify a definition or theorem. The reviewed expansion and conservative dependency DAG on this page are the actual family-local reading definitions.
