Understanding Divisibility by 6
To determine if a number is divisible by 6, we need to consider the properties of the numbers involved.
Divisibility Rules
- A number is divisible by 2 if its last digit is even (0, 2, 4, 6, or 8).
- A number is divisible by 3 if the sum of its digits is divisible by 3.
Combining the Rules
For a number to be divisible by 6, it must satisfy both conditions:
- Divisible by 2: The number must end with an even digit.
- Divisible by 3: The sum of its digits must be divisible by 3.
Why Option C is Correct
- Option A (Divisible by 2 only): This is incorrect because a number can be even but not divisible by 3.
- Option B (Divisible by 3 only): This is also incorrect since a number can be divisible by 3 but not even.
- Option C (Both 2 and 3): This is correct, as a number needs to meet both criteria to be divisible by 6.
- Option D (Last digit is 6): This is misleading; while 6 is even, not all numbers ending in 6 are divisible by 3.
Conclusion
Thus, a number is divisible by 6 if it is divisible by both 2 and 3, which confirms that option C is indeed the correct answer.
