Example 1:

\n\n
\nInput: n = 7\nOutput: 21\nExplanation: Numbers in the range [1, 7] that are divisible by 3, 5, or 7 are 3, 5, 6, 7. The sum of these numbers is 21.\n
\n\n

Example 2:

\n\n
\nInput: n = 10\nOutput: 40\nExplanation: Numbers in the range [1, 10] that are divisible by 3, 5, or 7 are 3, 5, 6, 7, 9, 10. The sum of these numbers is 40.\n
\n\n

Example 3:

\n\n
\nInput: n = 9\nOutput: 30\nExplanation: Numbers in the range [1, 9] that are divisible by 3, 5, or 7 are 3, 5, 6, 7, 9. The sum of these numbers is 30.\n
