Description

§

(gcd n_1 ...)
(lcm n_1 ...)

These procedures return the greatest common divisor or least common multiple of their arguments. The result is always non-negative.

(gcd 32 -36)            ===>  4
(gcd)                   ===>  0
(lcm 32 -36)            ===>  288
(lcm 32.0 -36)          ===>  288.0  ; inexact
(lcm)                   ===>  1
