Question:

The number 15287 is divisible by:

Options:

3

8

9

None of the above

Correct Answer:

None of the above

Explanation:

Following are the divisibility rules for different numbers:

Thus, we can say that 15287 is not divisible by 3, 8 and 9.

Divisibility by 3 = Sum of all the digits 1 + 5 + 2 + 8 + 7 = 23, as 23 is not divisible by 3 thus, 15287 is not divisible by 3.

Divisibility by 8 = Last 3 digits divisible by 3 i.e. 287 must be divisible by 8, which is not true. This, 15287 is not divisible by 8.

Divisibility by 9 = Sum of all digits 1 + 5 + 2 + 8 + 7 = 23, as 23 is not divisible by 9 thus, 15287 is not divisible by 9.
