The greatest factor of a set of numbers is the greatest number in the set. It will be a factor of itself. It will not be a factor of the other numbers in the set but that is not what the question requires.
To find the greatest COMMON factor, find the prime factorisation of each number.Multiply together each prime factor raised to the lowest power is any of the numbers.
That product is the greatest common factor.
