7.1.3  Least common multiple

The lcm command finds the least common multiple (LCM) of a set of integers or polynomials. (See also Section 11.2.7 for polynomials.)

• lcm can take seq, a sequence or list of integers or polynomials, as its only argument.
• lcm(seq) returns the LCM of the elements of s.
• Alternatively, lcm can take s and t, two lists of the same length containing integers or polynomials (alternatively, a matrix m with two rows whose elements are integers or polynomials).
• lcm(s,t) (or lcm(m)) returns the list whose kth element is the LCM of the kth elements of s and t (or the kth column of m).
