Not really. Your goal is to reduce the number to its prime factors, which can be done no matter which two factors you select. However, if you choose for each pair of factors a small one and a large one, it will take more steps to reduce the original number to its prime factors.
Here is an example.
Note: After you reach a Prime number in the factor tree, you don't usually continue carrying it down, but I did as a place holder, although I made them smaller in size. As each new prime factor is reached in the factor tree, I made it bold.
256
2 x 128
2 x (2x64)
2 x (2 x (2 x 32))
2 x (2 x (2 x (2x16)))
2 x (2 x (2 x (2 x (2x8))))
2 x (2 x (2 x (2 x (2 x (2x4)))))
2 x (2 x (2 x (2 x (2 x (2 x (2x2))))))
vs.
256
16 x 16
(4x4) x (4x4)
((2x2) x (2x2)) x ((2x2) x (2x2))
Not particularly, as long as they are prime.
Because you're not going to stop until all the factors are prime. It doesn't matter where you start. Consider 72: 72 8,9 4,2,9 4,2,3,3 2,2,2,3,3 72 36,2 18,2,2 9,2,2,2 3,3,2,2,2 Both are valid.
Factor both numbers. Select the factors they both have in common. Choose the largest (greatest) one.
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.
196: 2-2-2-2-11 1078: 2-7-7-11 Greatest common factor: 22 Method(s) used: # The method to find the greatest common factor of numbers is to find the prime factorizations of each one, select all matching prime factors, and then multiply. # An alternative method is to find all of the factors of each, and then select the greatest number that appears in each list. # The final method only applies to some numbers; if one of the number is a factor of the other, then that number is the greatest common factor. This is because all numbers are factors of themselves, and that is their greatest factor. If it is also a factor of the other number, then it is definitely the greatest common factor.
List the factors. 1, 2, 4, 7, 14, 28 1, 2, 4, 8, 16, 32 Select the factors on both lists. 1, 2 and 4 are the common factors.
no it does not matter what two factors you select to complete a factor tree (i just learned that today in class :D)
Yes, but it doesn't matter what two factors you select to start one.
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.
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.
nope it does not matter what 2 factors you choose.
yes it does matter because they must be compadible
It doesn't matter which two you start with, as long as all the factors are prime when you finish.
no not really.not all number can be divide bye the same number
no because no matter what number u pick they are all factors and it will ultimately come to the right answer
It doesn't matter what you select to start, but all the factors must be prime at the completion.
nope it does not matter what 2 factors you choose.
Yes, but it doesn't matter what two you select to start one.
