Which of the following numbers is divisible by 7?
24017
Checking divisibility by 7 for each option: \(21234\div7 = 3033.43\) (not exact).
\(24019\div7 = 3431.29\) (not exact), and \(23452\div7 = 3350.29\) (not exact).
\(24017\div7 = 3431\) exactly, since \(7\times3431=24017\).
Hence, 24017 is divisible by 7.
