find all the divisors of 0 in the ring Z_{6} of integers of modulo 6. in this system 2x3=0. so divisors of zero are 2 and 3. Again 4x3=0. So 4 is also a divisor of 0. ...... Is my approach right?

Yes, the "zero divisors" in are 2, 3, and 4. More generally, the zero divisors of are the prime divisors of n and their multiples.
