....The numbers DO NOT EXIST....
There are NO three numbers which when multiplied give a prime number.
coz, A prime number is a number which is divisible by one and itself, so if you get "this number" means it can be divisible by 1 and the other number.....contrary to its definition...

What about 2, 1 and -1. Multiplication is a prime number but not sure my answer is correct or not...

answer Oct 17, 2015 by Salil Agrawal
the product is -2 which is not prime...
remember prime number is a whole number divisible by 1 and itself....negative number is not a whole number............
i would say the numbers are -3, -1, 1 coz product is 3 which is prime(first condition) &
-1--3=1--1=2(second condition)

but -3 is not a number, it reads "negative of number three"......it just means "you don't have number 3 which you need" ......so its like you have a debt of number 3....

if negatives were numbers we wouldn't say a prime  number is divisible by only two numbers...one and itself...
I think -3, -1 and 1 is correct as the multiplication should be prime individual numbers can be anything.
But wonderful finding, will you like to answer the question :)
yes bro, I did

second answer.....

these are two numbers and what is needed is three numbers........
1=1, so 1 and 1 are not two numbers.....the are one number
