lcm(MonomialIdeal) -- least common multiple of all minimal generators

Synopsis

Description

This function is implemented in the engine, as it is used in many algorithms involving monomial ideals.

i1 : R = QQ[a..d];
i2 : I = monomialIdeal "a4,a3b6,a2b8c2,c4d5"

                     4   3 6   2 8 2   4 5
o2 = monomialIdeal (a , a b , a b c , c d )

o2 : MonomialIdeal of R
i3 : lcm I

      4 8 4 5
o3 = a b c d

o3 : R
i4 : first exponents lcm I

o4 = {4, 8, 4, 5}

o4 : List
