Question

Test the divisibility

Is $672$ divisible by $11$?

Answer 1

Explanation:

The divisibility rule of $11$ is take sum of odd places values and sum of even places values.

The difference of these two must be a zero or divisible by $11$ then the original number is divisible by $11$.

For the given number $672$ ,the sum of odd places is $2+6=8$ and even place is $7$.

The difference of these two is $1$ which is not divisible by $11$.

Hence, the number $672$ is not divisible by $11$.
