        "least common multiple"
        SYNTAX: X = lcm(A1, A2, ..., An)

        A1, ..., An are expressions whose values are elements in Z,
        polynomials over Z, Z/pZ, GF(p^n), n>=2 (where p is a prime) 
        or over number fields.

        X is assigned the least common multiple of A1, ..., An.

        Warning: If p > 2^30, the primality of p is not tested.
        

        Example 1: (correct)

                lcm(a1, (2 * 5 - 77 : 5), (sgn(234 + 23 - (log2(234)))))


        Example 2: (incorrect)

                lcm(2/3,14)
                
_ERR_NR_015


        Example 3: (correct)

                lcm( MOD( x^2*y + 3*y + x + 12 ), MOD( y*x + 3 ) )
