This is a simple question testing the student on their ability to calculate the lowest common multiple of two integers which are:
Part a) - coprime;
Part b) - where the greatest common divisor between the two integers is greater than one and not equal to either given number; and
Part c) - where one of the integer is a multiple of the other.

Saved a checkpoint:
The naive approach is to write out the times tables for each number, so I've put that in the advice.
I've reworded "a and b are coprime" to "a and b have no factors in common", which is hopefully a bit easier to agree with if you're not good at spotting primes.
