What else can I help you with?
How do you find out the common factors?
you use prime factorization
What strategy do you use to complete a list of factors?
you use a factor tree
How do you use prime factorization to find three common factors and three common multiples?
you multiply them together
How can you find the CFC of two factors?
To find the greatest common factor (GCF) of two factors, first list the factors of each number. Then, identify the common factors between them. The GCF is the largest of these common factors. Alternatively, you can use the prime factorization method, where you break down each number into its prime factors and multiply the lowest powers of all common prime factors.
What is the GCF of 28 using prime factors?
There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.
How do you use a factor tree to find the greatest common factor of 78 and 195?
Find out about factors and factor trees.
How can you use calculators to explore factors?
use common factors calculator
How do you use the prime factorizations to find the LCM of a and b?
a and b have no common prime factors. Their LCM is their product.
When is it useful to use factors and multiples?
Factors are useful when you're trying to reduce fractions. Multiples are useful when you're trying to find a least common denominator.
Did you use the factors of 100 to find the factors of 200 is so how?
The factors of 100 are included in the factors of 200, but I did not use one to find the other.
What is a strategy you can use to find the subject of the sentence?
turn the sentence into a question
Greatest common factor of 28?
One number can not have a common factor so there is NO GCF.. you need at least 2 You would use common factors for fractions, so to find the GCF you need 2 factors. (Assuming 1 and 28 here, it would be 28)
