That’s actually easy , No matter what , multiplication of those numbers are just to trick you.

Only focus on the word " 7 Consecutive numbers ". Let those numbers be n , n+ 1 . … n + 6.

So the smallest number is n and the largest number is 6. So the difference between largest and smallest number is n + 6 - n = 6.
