Question

Is $67321$ a multiple of $11$?

Answer 1

Check the divisibility using the Divisibility Test :

To check whether $67321$ is a multiple of $11$, we can apply the divisibility rule of $11$.
The divisibility by $11$ rule states that id the difference between the sum of odd place digit and even place digit is equal to $0$ or divisible by $11$ then the number is divisible by $11$.

Sum of the digits at odd places$=6+3+1=10$

Sum of the digits at even places$=7+2$

Difference$=10-9=1\ne 0$

That means $67321$ is not divisible by $11$

Hence $67321$ is not a multiple of $11$.
