Because 45 is not a factor of 60.
Factors, and by extension factor trees, refer to integers, not decimals.
Find out about factors and factor trees.
A factor tree shows the prime factors of the working number and can also be used as a visual demonstration to show the prime factors of the working number.
factor trees and prime factor trees are the same thing with different names.
Because 45 is not a factor of 60, whereas 15 and 30 are.
Factor trees are useful when you need to see the factors of a number. It is sometimes easier to see everything spread out.
3 is a prime number. Prime numbers don't have factor trees. The factors of 3 are 1 and 3.
Factor trees are for integers, not decimals.
Yes. Factors that complete a factor tree need to be prime. However, it doesn't matter what two factors you select to start a factor tree.
There is no factor tree nor factors of 57 as it is a prime number.
You break down the factors of a number until all the factors are prime. For example: 24 / \ 6 4 / \ 3x2 x 2x2 This factor tree was very easy, but there will be harder ones in the future. When all the numbers at the bottom of the tree are prime, you are finished. Factor trees may also be used to find the prime factorization of a number. PS: I'm sorry about the appearance of the tree. Once I published it, it became, and stayed that way. Real factor trees don't look like this. 24 is broken down into 6x4, because they are the factors. Since 24 is composite, you do not have to use 6x4. Then we break 6 into 3x2, and 4 into 2x2. Then 3x2x2x2 is a prime factorization. And you are also done with the factor tree!
NEVER! A factor tree is strictly division. Factors at the end of a factor tree should all be whole numbers.
