Which of the following number is divisible by 6?1. 123462. 123483. 123444. 12340

Answer» Correct Answer - Option 2 : 12348

Given:

Four numbers are given 12346, 12348, 12344, and 12340

Concept Used:

We check the divisibility of 2 and 3. The number which is divisible by 2 and 3 simultaneously will be divisible by 6.

Divisibility of 2: The number must end with 0, 2, 4, 6, 8.

Divisibility of 3: Sum of all digits of the given number should be divisible by 3

Calculation:

12346 : Last digit is 6 so divisible by 2 but sum of digits (1 + 2 + 3 + 4 + 6 = 16) is not divisible by 3, so number is not divisible by 6.

12348 : Last digit is 8 so divisible by 2 but sum of digits (1 + 2 + 3 + 4 + 8 = 18) is divisible by 3, so number is divisible by 6.

12344 : Last digit is 4 so divisible by 2 but sum of digits (1 + 2 + 3 + 4 + 4 = 14) is not divisible by 3, so number is not divisible by 6.

12340 : Last digit is 0 so divisible by 2 but sum of digits (1 + 2 + 3 + 4 + 0 = 10) is not divisible by 3, so number is not divisible by 6.

∴ 12348 is the number that is divisible by 6.
