45 15,3 5,3,3
45 15,3 5,3,3 81 27,3 9,3,3 3,3,3,3
The factor tree is as follows: 114 57,2 19,3,2
Since 61 is already prime, a factor tree is not necessary. The prime factorization of 51 is 3 x 17, which wouldn't make much of a tree. More like a factor shrub.
15,3 3,5,3
1,3,5,9,15,45
Because 45 is not a factor of 60.

45 15,3 5,3,3
Use a factor tree. 45 15,3 5,3,3
45 15,3 5,3,3
45 15,3 5,3,3
45 doesn't divide into 60 evenly.
45 15,3 5,3,3
Because 45 is not a factor of 60.
45 doesn't divide into 60 evenly.
