What is the least common multiple of 8?

Answer 1

Two or more whole numbers are required to determine their least common multiple. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more given whole numbers.
A least common multiple needs at least two arguments.

A common multiple of just one number makes no sense.

Answer 2

-- If you want the "least", then you only get one. If you asked for the least and

somebody gave you more than one, then you'd want to know which least was

less than the other least. 'Least' means the "most small", and there can only be

one of them.

-- "Common" means "same for both". There's nothing common about one single

thing or one single number. If you only have one thing or one number, then you

don't even think about anything common.

Answer 3

A single number cannot have a Lowest Common Multiple. A Lowest Common Multiple is used to compare two or more different numbers.
