Greatest number= Highest Common Factor,
In HCF you take the lowest value of the common prime numbers,
in this case all 3 numbers only have 2 and 3 as the common prime numbers, thus taking the lowest value of these 2 prime numbers would give you 2×3²=18, therefore HCF = 18 and that would be your answer :)
