The prime factors of 18 are 2, 3, and 3. The product of these prime factors is 18.
The distinct prime factors of 18 are 2 and 3. The product of these distinct prime factors is 6.
The factor pairs of 18 are (18,1)(9,2)(6,3) No pair consists of prime numbers. The best we can do is 2 x 3 x 3.

How do you find the LCM of a composite number?
You need at least two numbers to find an LCM. It doesn't matter whether they are prime or composite.
How do you find a pair of whole numbers whose product is 280 and whose LCM is 140?
They are 2 and 140 because their LCM is 140 and their product is 280
What are two numbers whose LCM is 2533?
They could be: 17 and 149
What two numbers whose LCM is 70?
10 and 35
What two even numbers whose LCM is 36 and whose GCF is 6?
As written, no numbers satisfy those conditions. 6 and 36 have a GCF of 6 and an LCM of 36.
What are two composite numbers whose LCM is 36?
6,364 and 9
What are two composite numbers whose LCM is 36 ( how to find)?
They are 4 and 9
Can LCM be found by composite numbers?
Not normally because the LCM of numbers are found by multiplying their highest prime factors
How do you find the LCM of a composite number?
You need at least two numbers to find an LCM. It doesn't matter whether they are prime or composite.
What conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
What are two numbers whose GCF is 20 and whose LCM is 100?
20 and 100.GCF is 20, and LCM is 100.
What is the LCM of 13 and 7?
LCM of 7 and 13Since 7 and 13 are both prime numbers, or numbers whose only factors are 1 and itself, the LCM can be found by multiplying 7 and 13 together. The answer will be 91.Though multiplying the numbers together when working with composite numbers MIGHT work, it only works 100% of the time when both numbers are prime. If one or both numbers are composite (have more factors than 1 and itself), multiples should be listed until a common one is found. That number will be the LCM.The LCM of 7 and 13 is 91.
Under what conditions is the LCM of two composite numbers simply the product of the two numbers?
When the numbers are relatively prime.
What are two composite numbers where the LCM is 16?
well, look at the factors of 16...we have 2,4,8, and16.So if we had LCM of 8 and 16, that would be 16 an both are composite
What is the pair of numbers whose gcf is 1 and LCM is 36?
The pair of numbers whose GCF is 1 and LCM is 36 is 9 and 4. The numbers should be greater than their GCF and less than their LCM.
What are three different composite numbers whose GCF60 and LCM1440 times 4?
60, 120 and 1440 have a GCF of 60 and an LCM of 1440. I'm not sure what the "times 4" refers to.
What two numbers whose GCF is 6 and whose LCM is 132?
12 and 66
