In part c)i), ii) and iii), I really wanted the individual factors to be listed for each number, and then for the common factors in each individual list to be highlighted but I didn't know how to do this and I think Chris mentioned something would have to be created in order to do this.

I think I would avoid 1 as an option altogether in part (b). Whether 1 is prime or not will trip up a lot of students but is unlikely to be of importance in their studies; I think it's more important to test their knowledge of whether a number is or isn't composite, rather than catch them out on (arguably) a technicality.
RE your problem in the comment below: h/6 is less than 6 ~50% of the time, so you could either re-think your variables, or use
sortto arrange into the correct order, for example set up a new list of numbers containing the factors...
There's a mix of singular and plural in the statement. I think I would write "A number that can be...".
"divided evenly by whole numbers" would be better as "divided without remainder..." to avoid confusion with even numbers.
Part (c) in the advice does not provide much additional informtation. I guess you haven't included all of the factors as it would be a pain! That's fine I think.

I think this is a really good question and it works well. Just a few comments
In the statement i would write a definition of composite as well as some students might not know what this means.
b) in the question i would write "Identify which of the following are prime numbers:" instead of "Identify the prime numbers from below."
One of the numbers here for me was 43, which is a prime number, however if you say it is a prime number it is marked incorrect as the displayed answer is that it is composite.
Good job getting the list of factors thing to work!
b) you could put the numbers in the table in the order that they appear in the question but it's up to you. I would also write "composite" instead of "not prime".
Also you could extend the table a little bit to the right, so that some numbers don't go onto a new line in the divisors column.

Also, the bit in the advice that says 'Whilst $1$ technically fits the criteria for a prime number, it is not considered a prime number' needs to be changed. $1$ does not meet the criteria for being a prime as it only divides by $1$, whereas all other primes have two distinct divisors, themselves and $1$.

Error in variable testing condition
There's an error in the condition you specified in the Variable testing tab. Variable values can't be generated until it's fixed.
No parts have been defined in this question.

Test that the marking algorithm works
Check that the marking algorithm works with different sets of variables and student answers using the interface below.
Create unit tests to save expected results and to document how the algorithm should work.
There's an error which means the marking algorithm can't run:
Click on a note's name to show or hide it. Only shown notes will be included when you create a unit test.
No unit tests have been defined. Enter an answer above, select one or more notes, and click the "Create a unit test" button.
The following tests check that the question is behaving as desired.
This test has not been run yet This test produces the expected output This test does not produce the expected output
This test is not currently producing the expected result. Fix the marking algorithm to produce the expected results detailed below or, if this test is out of date, update the test to accept the current values.
One or more notes in this test are no longer defined. If these notes are no longer needed, you should delete this test.

In order to create a variable replacement, you must define at least one variable and one other part.
|Variable||Answer to use||Must be answered?|
The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
