| In [[computational number theory]], the '''Adleman–Pomerance–Rumely primality test''' is an [[algorithm]] for determining whether a number is [[prime number|prime]]. Unlike other, more efficient algorithms for this purpose, it avoids the use of random numbers, so it is a [[deterministic algorithm|deterministic]] [[primality test]]. It is named after its discoverers, [[Leonard Adleman]], [[Carl Pomerance]], and [[Robert Rumely]]. The test involves arithmetic in [[cyclotomic field]]s.

| It was later improved by [[Henri Cohen (number theorist)|Henri Cohen]] and [[Hendrik Willem Lenstra]] and called APRT-CL (or APRCL). It is often used with [[UBASIC]] under the name APRT-CLE (APRT-CL extended) and can test primality of an integer ''n'' in time:
