lcm


    lcm(a,b)  


returns the LCM (least common multiple) of A and B, which must  
be one of the integer data types.  A and B may be conformable  
arrays; the semantics of the lcm call are the same as any other  
binary operation.  
The absolute values of A and B are taken before the operation  
commences; if either A or B is 0, the return value will be 0.
