#2#

Explanation:

First we find the factors of #-64n^2# and #-24n^2#

#-64n^2=nxxnxx-1xx2xx2xx2xx2xx2xx2#
#-24n^2=nxxnxx-1xx2xx2xx2xx3#

We take the lowest factor (#f>1, f="factor"#) of each.

The smallest number is #2#. We don't include #n# since a value less than #2# would either be #1# or a decimal which messes everything up, and a value greater than #2# will either be a number greater than #2# or a multiple of #2# (which we can just take 2 out of).
