Question

Characteristic of a finite ring having no divisor of zero is a prime number

Answer 1

The ring of integers modulo a prime number has no zero divisors other than 0. Since every nonzero element is a unit, this ring is a finite field. More generally, a division ring has no zero divisors except 0. A nonzero commutative ring whose only zero divisor is 0 is called an integral domain.

Answer 2

0 is the answer...............
