Which of the following numbers is NOT divisible by 8?

Question

Accepted Answer

A number is divisible by 8 if the number formed by its last three digits is divisible by 8.

Check each option:
1. 5544: Last three digits = 544. 544 ÷ 8 = 68 (exact), so divisible by 8.
2. 7344: Last three digits = 344. 344 ÷ 8 = 43 (exact), so divisible by 8.
3. 7497: Last three digits = 497. 497 ÷ 8 = 62.125 (not exact), so NOT divisible by 8.
4. 4608: Last three digits = 608. 608 ÷ 8 = 76 (exact), so divisible by 8.

Therefore, 7497 is NOT divisible by 8.
