Between Two Sets

    The directions for this challenge were quite confusing for me but this is how I solved it in c#

    {
    /*
     * Complete the 'getTotalX' function below.
     *
     * The function is expected to return an INTEGER.
     * The function accepts following parameters:
     *  1. INTEGER_ARRAY a
     *  2. INTEGER_ARRAY b
     */

    public static int getTotalX(List<int> a, List<int> b)
    {
        var start = a.Min();        
        var end = b.Max();
        var count = 0;
        for (var i = start; i <= end; i++)
        {
            if (a.areAllFactorsOf(i) && b.areAllMultiplesOf(i))
                count++;
        }
        return count;
    }

    public static bool areAllMultiplesOf(this List<int> values, int target)
    {
        return values.All(v => v % target == 0);
    }

    public static bool areAllFactorsOf(this List<int> values, int target)
    {
        return values.All(v => target % v == 0);
    }
}
