Is there supposed to be a remainder in the factor tree?
NEVER! A factor tree is strictly division. Factors at the end of a factor tree should all be whole numbers.
How would you find all of the factors of a composite number?
factor tree
Does it matter what two factors you complete to a factor tree?
In doing the factor tree, you can start with any two factors of the given number. These factors maybe prime or composite. But the resulting factors in the factor tree should always be prime numbers. It means that you have to continue factoring unless you ended up with all prime factors.
Does it matter that to fact is you select to complete a factor tree?
It doesn't matter what factors you select to start a factor tree. The only thing that matters about completing it is that all the factors are prime.
How do you work out the factor tree of 221?

What is a factor tree and how do youknow when a factor tree is complete?
When the bottom branch consists entirely of prime numbers.

No, as long as all the factors are prime when you're done.
What is the greatest common factor of 39 91 and 130?
Answer: 13Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 39 are 1, 3, 13, and 39.The factors of 91 are 1, 7, 13, and 91.The factors of 130 are 1, 2, 5, 10, 13, 26, 65, and 130.The common factors are 1 and 13. Therefore, the greatest common factor is 13.
The factor tree for 60 has all of the factors in the factor trees for 15 and 30 but not 45 Explain why this is true?
Because 45 is not a factor of 60.
When is a factor tree complete?
When you can no longer break down factors. when all the numbers at the bottom are prime!
What are common factors of 130?
All the factors of 130 are: 1, 2, 5, 10, 13, 26, 65, 130
