61 is already prime. It doesn't need a tree.
86 43 x 2
A Factor tree looks like this:... 42... / . \..2 ...21....... / . \.......3 . 7So the prime factors of 42 are 2 x 3 x 7
Divide 950 by 1, 2, 5, 10, 19 and 25. (950,1)(475,2)(190,5)(95,10)(50,19)(38,25)
Factor Tree of 20: ........20 ......../ \ .......4 5 ....../ \ .....2 2
Here is a factor tree of eight: 8 / \ 4 2 / \ 2 2
Prime Factor Tree: ........452 ........./ \ .......4 113 ....../ \ ....2...2
Factor Tree of 472: ...............472 ................/ \ ...... .....236 2 ............./ \ .........118 2 ........../ \ ........59 2

A commonly used factor tree for 132 is: 132 11 12 11 4 3 11 2 4 3 Another factor tree for 132 is: 132 66 2 22 3 2 11 2 3 2 Yet another factor tree for 132 is: 132 66 2 33 2 2 11 3 2 2 Hey for the first factor tree 4 isn't prime
I can't draw a factor tree here 76 / 2 = 38 38 / 2 = 19 Prime factorization is 2, 2, 19
2 and 5
2
factor tree of 68:(68) = 2 * (34)(34) = 2 * 17so prime factors are 2 * 2 * 17
(2)(2)(2)(2)
61 is already prime. It doesn't need a tree.
