1×24  2×12  3×8  4×6  6×4  8×3  12×2  24×1  Correct me if I′m wrong
$$\mathrm{1}×\mathrm{24} \\ $$$$\mathrm{2}×\mathrm{12} \\ $$$$\mathrm{3}×\mathrm{8} \\ $$$$\mathrm{4}×\mathrm{6} \\ $$$$\mathrm{6}×\mathrm{4} \\ $$$$\mathrm{8}×\mathrm{3} \\ $$$$\mathrm{12}×\mathrm{2} \\ $$$$\mathrm{24}×\mathrm{1} \\ $$$${Correct}\:{me}\:{if}\:{I}'{m}\:{wrong} \\ $$

if you mean Z_(24)  = Z/24Z  then 24 ∉ Z/24Z   and cannot be a zero divisor in Z/24Z
$${if}\:{you}\:{mean}\:{Z}_{\mathrm{24}} \:=\:\mathbb{Z}/\mathrm{24}\mathbb{Z} \\ $$$${then}\:\mathrm{24}\:\notin\:\mathbb{Z}/\mathrm{24}\mathbb{Z}\: \\ $$$${and}\:{cannot}\:{be}\:{a}\:{zero}\:{divisor}\:{in}\:\mathbb{Z}/\mathrm{24}\mathbb{Z} \\ $$
