Common multiple. Incidentally, it need not be the least common multiple. Using the least common multiple instead of any common multiple means that the numbers involved in the calculations are smaller but does not mathematically alter the results.
There is not a least common multiple of a single number, such as 130, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common.
