Is the LCM of a prime number and a composite number a multiple of the prime number?
Yes, the least common multiple (LCM) of a prime number and a composite number will always be a multiple of the prime number. This is because the LCM is the smallest number that is a multiple of both numbers. Since the prime number is a factor of itself and the LCM is a multiple of both numbers, the LCM will always be a multiple of the prime number.
What is the least common multiple of 27 and B?
LCM of 27 & 5 = 27 x 5 = 135. LCM of a prime number and a composite number is equal to their product if the composite number is not a multiple of the prime number.
What is the LCM of 357?
The LCM of a single number is itself. To find the LCM requires two or more numbers.
Why we never asked to find a LCM of a pair of number?
You could only find the LCM of a PAIR of numbers.
How do you find the LCM of 27?
By comparing it with another number.
What is the least common multiple of 20 and 41?
LCM of a prime number and a composite number is always equal to their product if the composite number is not a multiple of the prime number. Here, 41 is a prime number and 20 is a composite number. Therefore LCM(20,41) = 20 x 41 = 820

What are two composite numbers whose LCM is 36 ( how to find)?
They are 4 and 9
What Method used to find composite numbers?
To find a composite number, check if the number can be divided by 2,3,4,5, ect. If it can, it`s composite. If not, it`s prime.
What is the lcm of 5 and 49?
LCM of a prime number and a composite number is equal to their product if the latter is not divisible by the former. 5 is a prime number and 49 is a composite number. 49 is not divisible by 5. So, LCM(5,49) = 5 x 49 = 245. Actually the reason behind this is that both(5 and 49) do not share any common factors except 1, so the LCM is equal to the product.
How do you find the composite number?
Factor it. Once you find a third factor, it's composite.
What is the least common multiple of 27 and B?
LCM of 27 & 5 = 27 x 5 = 135. LCM of a prime number and a composite number is equal to their product if the composite number is not a multiple of the prime number.
What is the LCM of 3420?
Another number is needed to find LCM
What number has a prime greatest common factor and a LCM that is composite?
There can be no such number.The GCF and LCM are numbers which are COMMON to two or more integers. A single number has nothing else to have something in common with. The greatest factor and the least multiple of any single number is itself and so the question requires a number which is prime (GCF) and composite (LCM). Clearly, such a number cannot exist.
How do you determine a composite number?
Composite numbers have more than two factors. Once you find a third factor, you know your number is composite.
What is the LCM of 1268?
The LCM of this number is itself. To find the LCM requires two or more numbers.
How do you find the LCM of 3 numbers through the common division method?
Find the LCM of the first two numbers and then find the LCM of that number and the third one. That answer will be the LCM of all three.
