Choose the odd one out: 3, 5, 7, 11, 14, 17
Show answer & explanation
Correct answer: C
Explanation
3: Divisible only by 1 and itself (3) → Prime number
5: Divisible only by 1 and itself (5) → Prime number
7: Divisible only by 1 and itself (7) → Prime number
11: Divisible only by 1 and itself (11) → Prime number
14: It is exactly divisible by 2 and 7 in addition to 1 and 14 → Composite number (Even number)
17: Divisible only by 1 and itself (17) → Prime number
Conclusion:
All other numbers in the series (3, 5, 7, 11, 17) are prime numbers, while 14 is the only composite (and even) number. Therefore, 14 is the odd one out in this group.
The correct answer is 14.
