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.
It's not where you start, it's where you finish. It doesn't matter what factors you select to start a factor tree, as long as all the factors are prime when you finish.
no
39 3,13
The purpose of a factor tree is to divide a number into prime factors. 1 is not a prime number.
When the bottom branch consists entirely of prime numbers.
Its factors are: 1, 17, 23 and 391
As a product of its prime factors: 2*1423 = 2846
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.
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.
nope it does not matter what 2 factors you choose.
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.
No, as long as all the factors are prime when you're done.
yes it does matter because they must be compadible
It doesn't matter what two factors you select to start a factor tree. As long as you do it correctly, the bottom branch will always be all prime numbers.
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
