which number is not a factor of 124
31, 12,4,or 2
False. The least common multiple (LCM) of a list of numbers is the smallest number that is divisible by each number in the list, not just a multiple. In other words, the LCM is the smallest number that is a common multiple of all the numbers in the list.
There is no "most common" multiple of two or more numbers, but there is a greatest common multiple if that's what you mean. But for multiples, the list of common ones goes on and on and on, since every single number in the universe is a multiple.
When you are finding common factors, one method is to list the factors.
A common multiple
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
The least common multiple of the numbers 350 and 140 is 700.
LCM or least common multiple of 24 and 18 is 72 so any multiple of 72 is a common multiple To list them all we can write {m| m=72n for some natural number n) which means the set of all m such that m is a natural number multiple of 72 Or you can just say all common multiples of 24 and 18 are 72k where k = 1,2,3....
The "least" common multiple of 12 and 18 will be 36.
The list is endless because there is an infinite number of common multiples for 3 and 5. 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 (LCM) of 3 and 5 is 15.
That's the least common multiple, or LCM.
you list all the multiples of each number until you come to the first number that is in all columns
The list would be endless because there is an infinite number of common multiples for 21 and 13. 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 leastor lowest common multiple (LCM) of 21 and 13 is 273.
