No, because the number of common multiples of any two nonzero numbers is infinite.

A non-example of divisor ring of integers, a division ring or a nonzero commutative ring that has no zero divisors except 0.
A nonzero multiple of a number is a multiple which is not equal to 0.
To the nearest ten, 70
The greatest nonzero place is the number closest to the left (or the greatest number) that is not zero. So in this example, that would be the 8. So you would round the 8 up to a 9 (since 6 is greater than 4). So your answer would be 0.9
