What is the least common multiple of a group of four numbers explain and give an example?
The least common multiple, or LCM, is the smallest number that all four numbers will divide into evenly with no remainder. Example: 30, 42, 54, 60
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
2 x 3 x 3 x 3 = 54
2 x 2 x 3 x 5 = 60
Combine the factors, eliminating duplicates.
2 x 2 x 3 x 3 x 3 x 5 x 7 = 3780, the LCM

Will two numbers always have a common multiple?
A number is an exact multiple of each of a group of numbers. For example, 15 and 30 are common multiple of 3 and 5.
What is a common multiple?
A common multiple is a number that two or more other numbers can both go into. For example, a common multiple of 2, 4, and 6 would be 12.Not sure what you mean by a "comman" multiple, but a commonmultiple of a set of numbers is a number that is a multiple of each number in the set. That is, it is in the multiplication table of each of the numbers in the set. Note, though, that for this purpose, the multiplication tables do not stop at 10 times or 12 times.All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples.18 is a multiple of 6.18 is a multiple of 9.18 is a common multiple of 6 and 9.All numbers have multiples. Some numbers have the same multiples as other numbers. These are called "common multiples."12 is a multiple of 3.12 is a multiple of 4.12 is a common multiple of 3 and 4.
Can the LCM of 9 and 17 be less than 17 Explain.?
No. A common multiple is a multiple of both numbers. There is no multiple of 17 that is less than 17.
What does lowest common multiple mean?
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
What is the least common multiple of two numbers if one number is a multiple of the other and what is an example?
The LCM is the multiple. The LCM of 9 and 3 is 9.
What is the least common multiple of two numbers that have no common factor greater than one?
It depends on what the numbers are. For example, if the prime numbers you were talking about were 3 and 7, the least common multiple would be 21. If your numbers were 2 and 3, it would be 6.
What is meant by least common multiple of two or more numbers?
The least common multiple of two or more numbers is the number that both of them can multiply into evenly. For example, the greatest common factor of 4 and 5 is 20.
Why do you have least common multiple and not greatest common multiple?
There isn't a GCM (greatest common multiple) because multiples have an unlimited supply; numbers have no end. For example, the number 10,000,000,000,000 is smaller than 10,000,000,000,000,000,000,000.
What is the common multiple?
It's a number that two or more other numbers can both go into. For example, a common multiple of 2, 4, and 6 would be 12.
What is an example of a largest common multiple?
This cannot be answered because the common multiples of any two or more numbers are infinite.
Can you always find the LCM for two numbers by muiltiplying them together?
No, this will find a common multiple, but not always the least. For example, 2 and 4 have a least common multiple of 4 but if you multiply them you get 8. In fact, the LCM will only be the product of two numbers if the numbers have no common factors. We call numbers with no common factors relatively prime.
What is the greatest common multiple for 36 and 64?
There is no such thing as a "greatest common multiple" of a set of numbers. Once you find ANY common multiple (for example, by multiplying the two numbers), that common multiple times 2, or times 3, etc. will also be a common multiple.For many practical problems, you are usually required to find either:The least common multiple, or The greatest common factor.
