-ve numbers as well as zero are multiples of integers, -2,-4,-6 are consequctive multiples of 2.
zero is also a multiple of any integer so divisable by all integers.

0/3 = 0 no remainder here so it is divisable by 3.

If you are asking about -ve numbers being factors in sense of prime factorization of a number then no.

if we have an expression like (x-3)(x-2)<0 then we say that one of the factor is negative right?
either x-3 or x-2 so how come factors cannot be negative?
