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.


Why can't you find the greatest common multiple in a group of numbers?

You can't find the greatest common multiple in any amount of numbers, the number would be infinite.


What is common to 2 or more numbers in a group and has the least value of all common multiples for those numbers?

That's the least common multiple, or LCM.


What is the smallest number that a group of numbers will evenly divide?

It is called the "least common multiple".


Shared multiples of two or more numbers are called?

The Least Common Multiple (or Lowest Common Multiple) of a group of numbers, called the LCM, is the smallest number that's a multiple of all the numbers. For instance, the LCM of 16 and 20 is 80; 80 is the smallest number that's both a multiple of 16 and a multiple of 20.


What method would be useful to find the Least common multiple of a group of four number?

Prime factorization.


What is the different between common and multiple?

A multiple is a number that the original number divides evenly into.Ex. 120 is a multiple of 60.A common multiple is a number that a pair/group of numbers both divide evenly into.Ex. 12 is a common multiple of 2, 3, 4, and 6.


What are the common multiples of 42 and 60?

One way to find a common multiple of any group of numbers is to multiply them all (to find the product). So one common multiple of 42 and 60 is 42x60=2520 This will not however, always give the LOWEST common multiple, which in this case is 420.


What is the lowest common factor of 6 10 15?

The lowest common FACTOR of any set of numbers is 1. Perhaps you meant the Lowest Common MULTIPLE, which for 6, 10, 15 is 30. Or you meant the HIGHEST Common Factor, which for 6, 10, 15 is 1.


Which group of numbers has a greatest common factor of 6?

Asking a multiple choice question without providing the choices doesn't really seem fair.


What is the least common factor of 10 and 35?

-- The least common factor of any group of whole numbers is ' 1 '.-- The greatest common factor of 10 and 35 is 5 .-- The least common multiple LCM(10, 35) = 70


What is the least common multiple of 1422704?

You need at least two numbers to find an LCM. If that group is more than one number, put spaces between them.
