When can you multiply two numbers together to get the least common multiple?
When they have no common prime factors.
What are common multiples and least common multiples?
All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples. The smallest of these is known as the least common multiple. Common multiples of 3 and 4 include 12, 24, 36 and so on. The LCM of 3 and 4 is 12.
What is the least common multiple of 34?
There is no LCM for less than two numbers. LCM is the multiple of the highest power of prime factors in two or more numbers. Example: LCM 0f 9, 15, and 25 is 225, which is the multiple of the highest power of prime factors in 9, 15, and 25 (32 x 52).
How to find LCM?
LCM is the multiple of the highest power of prime factors in the numbers. Example: LCM 0f 9 and 25 is 225, which is the multiple of the highest power of prime factors in 9 and 25 (32 x 52).
If 3 is not a common factor of a pair of numbers what other numbers cant be common factors explain?
If they don't both divide by 3 then no multiple of 3 can be a common factor...
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 are the steps in finding the least common multiple of two numbers?
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
What r the 3 numbers that have 2 4 and 8 as factors?
Calculate the least common multiple of the three numbers. Any multiple of that has all those numbers as factors.
What is the difference between a common multiple and a common factor?
Factors go into numbers, numbers go into multiples.
When the greatest common factor is 1 is the least common multiple of these numbers always the product of the numbers?
Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.
When can you multiply two numbers together to get the least common multiple?
When they have no common prime factors.
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 are the common factors of numbers?
The factors that they share. Example: 30 and 42 1,2,3,5,6,10,15,30 1,2,3,6,7,14,21,42 1,2,3 and 6 are the common factors, the factors in common.
When will the Least Common Multiple LCM of two numbers be the product?
When the two numbers have no common factors. This is called relatively prime.
Do two whole numbers always have a least common multiple?
Yes. If A and B are any two whole numbers then A*B is a common multiple. Then either A*B is the least common multiple of A and B or one of its factors is.
How can you find the least common multiple of 3 numbers?
By finding their prime factors
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.
