    Prime factorization starts at 2, I'm not sure what you mean. Anyway, if you wanted to exclude 0 you could say "positive integers", it's not that hard.

      1 also has a unique 'empty' prime factorization, while zero has none.
      You can also say "nonnegative integers", if you want to include zero.
