Question

Using divisibility tests, determine which of following numbers are divisible by 6:
a) 1258 b) 901352

Answer 1

(i) As the given number ends with 8. Hence, the last digit is divisible by 2. So number is divisible by 2.

On adding all the digits of the given number, we obtain the sum as 16 which is not divisible by 3. So the number is not divisible by 3
∴ The number 1258 is not divisible by 6.

(ii) As the given number ends with 2. Hence, the last digit is divisible by 2. So number is divisible by 2.

On adding all the digits of the given number, we obtain the sum as 20 which is not divisible by 3. So the number is not divisible by 3.
∴ The number 1258 is not divisible by 6.
