How can you determine whether the gcf of two numbers is one by looking at their prime factorizations?
If there are no prime factors in common, the GCF is 1.
Greatest common factor on 105 168 224 using prime factorizations?
7
How do you find the greatest common factor of 4 digit numbers?
Example: 30 and 42 List the factors. 1,2,3,5,6,10,15,30 1,2,3,6,7,14,21,42 Select the common factors. 1,2,3 and 6, the GCF.
Do you do a factor rainbow for greatest common factor?
You do a factor rainbow to find a prime factorization. You compare prime factorizations to find a greatest common factor.
List two methods that can be used to find the greatest common factor of a set of numbers?
Prime factorization and the Euclidean algorithm
Which term makes this sentence true the greatest least of the common factors of two or more numbers is the greatest least common factor of the numbers?
Actually, both can be true, but the answer your teacher is probably looking for is "greatest."
Do factor trees always work for determining the greatest common factors?
If you construct them correctly, factor trees always work to determine the prime factorization of a number. Once you compare the prime factorizations of two or more numbers, it is relatively easy to find the greatest common factor of them from there.
How can you determine from the prime factorization whether the least common multiple of two numbers is the product of the numbers?
If the prime factorizations have no factors in common, the LCM is the product of them.
How do you find the greatest common factor in the hundreds and thousands?
The same as with smaller numbers. Every composite number, no matter the size, can be expressed as the product of prime factors. Comparing prime factorizations will give you the GCF.
What are the common factors of 8 and 96?
Since you're not looking for the numbers with the decimals, the greatest common factor would just be 4.
How can you determine from the prime factorizations whether the least common multiple of two numbers is the product of the numbers or is less than the product of the two numbers?
If none of the prime factors are in common, the LCM will be the product of the two.
What is the greatest common factor of 80?
The word "common" means "same for all". There's nothing common about a single thing, There's no common factor of a single number. Before you can start looking for common factors, you need at least 2 different numbers.
