The given set is,

This set is comprised of all negative integers. So symbol Z should be used in this case.
The set builder notation for this set is,

(2x10)+(4x1)+(3x1/10)+(5x1/100)+(7x1/1000)

Answer:
It is a multiple of 8
Step-by-step explanation:
The product may or may not be a factor of 8. We usually think of the factors of an integer as being positive integers, so the factors of 8 would be 1, 2, 4, or 8. If 8n is to be a factor of 8, then n must be 1/8, 1/4, 1/2, or 1. This will not be the case in general.
__
The product of 8 and any number is a multiple of 8. (Again, we usually think of a multiple of 8 as being an integer, which would require the number n to be an integer.)
__
No product of two (integer) numbers is a prime number. If 8n is to be a prime, then the value of n must be <em>(some prime number)/8</em>. Again, this will not be the case in general.
__
n is a factor of the product; not the other way around.
