<P> In arithmetic and number theory , the least common multiple , lowest common multiple , or smallest common multiple of two integers a and b , usually denoted by LCM ( a , b ) , is the smallest positive integer that is divisible by both a and b . Since division of integers by zero is undefined , this definition has meaning only if a and b are both different from zero . However , some authors define lcm ( a , 0 ) as 0 for all a , which is the result of taking the lcm to be the least upper bound in the lattice of divisibility . </P>
