The product of four continuous natural numbers is 3024, and their sum is: How to calculate?

This is very simple. Four continuous natural numbers are all integers. 3024 digits are 4, so it is impossible for them to have a number with 5 or 0 digits. Therefore, these four numbers must be 1234 or 6789 digits. Since the minimum product of four two digits is more than five digits, these four numbers can only be 6.7.8.9, so their sum is 6 + 7 + 8 + 9 = 30
