lcm(+Number1, +Number2, -Result)

   Unifies Results with the Least Common Multiple of Number1 and Number2

Arguments
   Number1             Integer.
   Number2             Integer.
   Result              Output: integer.

Type
   Arithmetic

Description
   This predicate is used by the ECLiPSe compiler to expand evaluable
   arithmetic expressions.  So the call to lcm(Number1, Number2, Result) is
   equivalent to

    Result is lcm(Number1, Number2)

    which should be preferred for portability.

   The Least Common Multiple operation is only defined on integer arguments.

   In coroutining mode, if Number1 or Number2 are uninstantiated, the call
   is delayed until these variables are instantiated.




Modes and Determinism
   lcm(+, +, -) is det

Exceptions
     4 --- Number1 or Number2 is not instantiated (non-coroutining mode    only).
     5 --- Number1 or Number2 is a number but not an integer.
    24 --- Number1 or Number2 is not of a numeric type.

Examples
   
Success:
    Result is lcm(9, 15).		 % gives Result = 45
    Result is lcm(-9, 15).		 % gives Result = 45
    X is lcm(2358352782,97895234896224). % gives X = 38478583260342225282528 

Error:
    Result is lcm(1.0, 2).         (Error 5).
