Question

Check the divisibility of the following numbers by $9$:

$5354781$

Answer 1

Divisibility rule by $9$:

A number is said to be divisible by $9$, if the sum of its digits is divisible by $9$.

Here, sum of digits of $5354781$ is $5+3+5+4+7+8+1=33$.

Since, $33$ itself is not divisible by $9$, therefore $5354781$ is also not divisible by $9$.

Thus, $5354781$ is not divisible by $9$.
