Question

Check the divisibility of $60169803$ by $8$.

Answer 1

According to the divisibility by $8$:

A number is divisible by $8$, if the number formed by the last three digits (i.e., digits at hundreds, tens and units place) is divisible by $8$.

For example:

Consider the number $6437536$

the numbers formed by hundreds, tens, and unit digits (last three-digit) $=536$ which is divisible by $8$. Therefore, the number $6437536$ is divisible by $8$.

Now, we have $60169803$,

the number formed by hundreds, tens, and unit digits (last three-digit) $=803$ which is not divisible by $8$.

Thus, $60169803$ is not divisible by $8$.
