#128=2xx2xx2xx2xx2xx2xx2#

Explanation:

Factor tree is a diagram, where we find factors of a number, here it is given as #128#, then the factors of those numbers and continue, till we can't factor any more.

It is obvious that the ends will all be the prime factors of the original number.

As #128=8xx16#, we do this as per diagram below.
