What if there is no LCM in a fraction problem?
There is always going to be a LCM. Just multiply the two numbers together to get the a common multiple if you cant find one because the two numbers multiplied together is a common multiple.
What is a 2 numbers who have a least common multiple and a if you multiply them together you get the answer of there least common multiple?
Two numbers that are relatively prime (have a GCF of 1) like 25 and 36, will have their product as the LCM.
How do you do least common denominator of 2 and 7?
The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.
How do you find the least common multiple of 7 and 11?
Multiply them together.
How do you find the least common multiple of 4 and 7?
Multiply them together.
How do you get a common multiple?
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.
How do you find the common multiple?
Multiply your numbers together.
What is the common multiple of?
Multiply any two numbers together. Their product will be a common multiple of the two.

Why do you multiply the prime numbers together to find the LCM?
You multiply numbers because you're trying to find a multiple. You multiply prime numbers because you're trying to find the smallest common number. You could multiply common composite factors, but the result wouldn't necessarily be least.

What is the common multiple of 89 and12?
For any two numbers, if you multiply them together, you get a common multiple.In this case, this also happens to be the LEAST common multiple, since 89 and 12 have no common prime factors.
What is the least common multiple of 35 and 22?
The least common multiple of 35 and 22 is 385.
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.
How do you get the least common multiple of 10 and three?
Multiply them together.
How do you get the least common multiple of 13 and 16?
Multiply them together.
