Since 5 is a prime, it looks like the end of a branch.
65 / \ 13 5
Factor tree for 51: 51 * 1 or 17 * 3 Factor tree for 255: 255 * 1 or 51 * 5
There are many different ways the tree could look, but here is one.4255 x 855 x 5 x 17
IT IS PRIME there is no factor tree
45 15,3 5,3,3
35 5,7 Not much of a tree. More like a factor shrub.
Factor Tree of 20: ........20 ......../ \ .......4 5 ....../ \ .....2 2
5*5
You can't really draw a factor tree with a keyboard. The arithmetic goes like this: 315 = 5x63 = 5x3x21 = 5x3x3x7. 5, 3, 3 and 7 will be the 'leaves' at the bottom of your tree.
A factor tree of 1575: 1575 / \ 5 325 / \ 5 65 / \ 5 13 Answer: 5*5*5*13 or 13*53
2 and 5
125 5 x 25 5 x (5x5) Since 5 is a prime number, the factor tree is complete.
