You need at least two numbers to find an LCM.

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.

The lowest common factor (the smallest positive whole number which divides into all the numbers without any remainder) of 3, 4, 16 is 1, as it is for any set of numbers. The highest common factor (the largest positive whole number which divides into all the numbers without any remainder) is also 1. The lowest common multiple ((the smallest positive whole number into which divide all the numbers without any remainder, ie the smallest positive whole number which is a multiple of all the numbers) is 48.

There is an infinite number of common multiples for 18 and 30 A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple of 18 and 30 is 90.

There is an infinite number of common multiples for 36 and 48. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple of 36 and 48 is 144.

Lowest Common Multiple-the smallest number that is a multiple of all the numbers in a given set; same as least common multiple. Example-for 6,9, and 18, 18 is the lowest common multiple. =]its lowest common multiple

That depends on the other number because to have the lowest common multiple there has to be two numbers or more

Lowest common multiple. Say you have 2 numbers, 6 and 9. Their lowest common multiple is 18. This is the lowest number that both numbers will divide into evenly

A single number cannot have a lowest common multiple - a lowest common multiple is used to compare two or more different numbers.

you can't find the lowest common multiple of one number. you need two numbers i.e. the lowest common multiple of 640 and 820 is 26240 because it is the lowest number that both 640 and 820 are a factor of. You have to have two numbers genius

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! The least multiple of a number is itself.

The lowest common multiple of two numbers, a and bis the smallest number that is divisible by both a and b. There is no such thing as a lowest common multiple of a single number.In the case that this question is asking the lowest common multiple of 3 and 2, the answer is 6.

Normally the term, "lowest common multiple" is used with at least two numbers. If you only have one number, then how does the word, "common" have any meaning? Nevertheless, to answer your question as it stands, the number itself is the lowest common multiple. Multiply it by two to get the next lowest multiple, then by 3 for the next lowest, etc.

You need at least two numbers to find an LCM.

There is no answer. There cannot be a lowest common multiple of a single number, such as 30, because "common multiple" means a multiple that two or more numbers have in common. Likewise, there cannot be a highest common factor of a single number, such as 3, because "common factor" means a factor that two or more numbers have in common.

the Least Common Multiple, or "LCM" of a number is the lowest possible number that a set of numbers can go into. for example, if you have a set of 12 and 7, the lowest common multiple would be 84, because that's the lowest number they both go into.

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