The common multiples of two or more integers are called their common multiples, and the smallest common multiple other than 0 is called the least common multiple of these integers.
The least common multiples of the integers a and b are denoted as [a, b]. Similarly, the least common multiples of the a, b, and c are denoted as [a, b, c]. The least common multiples of the multiple integers have the same notation.
The multiples are only the smallest and not the largest, because multiples of two numbers can be infinite.
