Z is not a field. A field need two operations - typically addition and multiplication when we talk about the regular sets of numbers, but Z does not have an inverse for multiplication since for example 5 does not have an integer which when multiplied by 5
Set of Integers not a field
https://math.stackexchange.com
I read that the set of Integers Z is not a field because it does not satisfy the Identity Axiom X×X−1=1.
Why isnt Z or N a field?

How to prove Z[i] is a ring but not a field?
https://math.stackexchange.com
The quotient field of Z[i] obviously is Q(i), which is different from Z[i]. Hence Z[i] cannot be a field, because the quotient field of an ...
Integers do not form Field
https://proofwiki.org
The integers (Z,+,×) do not form a field. Proof: For (Z,+,×) to be a field, it would require that all elements of Z have an inverse.
Why is Z not a field?
https://www.reddit.com
In order for a set to be a field it must contain the multiplicative inverse if each of its elements with the exception of the additive inverse.
Is Z<4> a field?
https://www.quora.com
Z/<4> = Z/4Z is not a field because the nonzero element 2+4Z is not invertible. Actually this element is a zero divisor, as its square is the ...
