Answer
Correct Answer: 3
Explanation
Given data
- Number: 918762
- Divisibility condition: divisible by 8
Concept / Approach
- A number is divisible by 8 if its last three digits form a number divisible by 8.
Step-by-step calculation
Last three digits = 62 → consider 602, 612, 622, 632, 642, 652, 662, 672, 682, 692Check divisibility by 8: 632 ÷ 8 = 79 (exact)Smallest digit that works is 3
Verification
Other smaller candidates fail: 602 mod 8 = 2, 612 mod 8 = 4, 622 mod 8 = 6.
Common pitfalls
- Testing the full number unnecessarily; only the last three digits matter for divisibility by 8.
Final Answer
Smallest possible digit is 3.
