You need at least two numbers to find an LCM.

All composite numbers have prime factors and these are used to find the highest common factor of 2 or more numbers and they are also used in finding the lowest common multiple of 2 or more numbers. Composite numbers have 2 or more factors while prime numbers have only 2 factors which are themselves and one

To find out the difference between prime numbers and composite numbers because prime numbers are useful in finding the lowest common multiple of numbers or the highest common factor of numbers.

LCM means the lowest common multiple of two or more numbers

Yes, and of the composite number. LCM stands for Least Common Multiple. It's a multiple that's common to both of them.

The easiest way is to multiply the numbers together. The answer won't necessarily be the least common multiple, but it will be a common multiple. The easiest way to get a common multiple is to multiply the numbers together. The result will not necessarily be the least common multiple, but it will be a common multiple.

A common multiple is a multiple that two or more given numbers have in common. 16 is not a common multiple of 7 and 8. 16 is a common multiple of 4 and 8. So, it depends on the numbers for which you are trying to find a common multiple.

All numbers with a least common multiple, have that multiple as a factor.

The least common multiple is one of the numbers when one of the numbers is a multiple of the other.

It's the same process as composite numbers. Factor them. Combine the factors, eliminating duplicates. If they have no common factors, the LCM is their product.

The least common multiple of the numbers 2,357 and 11 is 25,927.The least common multiple of the numbers 23, 57 and 11 is 14,421.

?

They are both rational integers or whole numbers Their lowest common multiple is 168

Never. The greatest common multiple of any two numbers is infinite.

The product of the GCF and the LCM is equal to the product of the original two numbers.

The greatest common multiple of any set of numbers is infinite. The greatest common multiple of any set of numbers will never be one.

to find the least common multiple of two numbers you must list the factors then you can find out their least common multiple of the two numbers

There is not a common multiple or least common multiple of a single number, such as 30, because there cannot be any common multiples 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.

The least common multiple of the numbers 8 and 6 is 24.

The greatest common multiple of any two numbers is infinite.
