D.4.22.23 computemcm

Procedure from library resbin.lib (see resbin_lib).

Usage:
computemcm(Eolist); Eolist list

Return:
an integer, the least common multiple of the denominators of the E-orders

Note:
Make the same as lcmofall but for one chart. NECESSARY BECAUSE THE E-ORDERS ARE OF TYPE NUMBER!!

Example:
 
LIB "resbin.lib";
ring r = 0,(x(1..2)),dp;
ideal J=x(1)^3-x(1)*x(2)^3;
list L=Eresol(J);   // 8 charts, rational exponents
L[8][2][2];         // maximal E-order at the first chart
==> [1]:
==>    3
==> [2]:
==>    9/2
computemcm(L[8][2][2]);
==> 2
