You can easily make a factor tree by dividing the number in half. This strategy is useful if the number is divisible by 2.
112- a number where you cant think of immediate factors
divide it in 2:
56,2
again:
28,2,2
14,2,2,2
7,2,2,2,2
7 is prime, making this tree complete.
If the number isn't divisible by 2 that it could become more complicated. most of the time, you can find a factor quickly and then just begin dividing in half.
No you cannot. You might want to try the factor tree for 27.
No.
109 109 x 1 This is all there is to the factor tree, because 109 is a prime number. Normally, I wouldn't use 1 in a factor tree, but I do in this case to make it clear that I have done a factor tree, since 109 is only divisible by itself and 1.
IT IS PRIME there is no factor tree
The factor tree of 50:5025,25,5,25025,25,5,2
The factor tree is as follows: 114 57,2 19,3,2
no
Oh, dude, making a factor tree for 7 is like, super easy. You just start with 7 at the top, and then realize that 7 is a prime number, so it only has 1 and 7 as factors. So, your factor tree is basically just a stick with 7 at the top. Voilà!
No.
yes
991 is already prime. No tree is required.
13 is a prime number. It doesn't have a tree because its only prime factor is itself.
No you cannot. You might want to try the factor tree for 27.

15,3 3,5,3
