What is the least common multiple of 15?

Answer 1

At least two numbers must be given to have a lowest common multiple. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more given whole numbers.

Answer 2

It is not possible to give a sensible answer to this question. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!

Answer 3

It is not possible to give a sensible answer to this question for two reasons.

• The lowest common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!
• An LCM makes no sense in the context of fractional numbers. This is because every number is a multiple of any non-zero number. So 3.72 is a multiple if 1.5 since 1.5*2.48 = 3.72.

Answer 4

Well, honey, the least common multiple of 15 is 15 itself. It's a Prime number, so it doesn't have any other factors besides 1 and itself. So, in this case, the answer is as simple as it gets.

Answer 5

You need at least two numbers to find an LCM.
