60 30,2 15,2,2 5,3,2,2 2 x 2 x 3 x 5 = 60
IT IS PRIME there is no factor tree
The factor tree of 50:5025,25,5,25025,25,5,2

Because 45 is not a factor of 60.

60 30,2 15,2,2 5,3,2,2
60 30,2 15,2,2 5,3,2,2
45 doesn't divide into 60 evenly.
30,2 15,2,2 5,3,2,2
Because 45 is not a factor of 60.
45 doesn't divide into 60 evenly.
as you can obviously see the bottom of a factor tree would be the curious numbers of 2,2,3,5
use a factor tree
