Giải giúp em câu a;b;c;d với ạ gấpp🥺

Giải thích các bước giải:

Ta có:

\(\begin{array}{l}
a,\\
18 = {2.3^2}\\
80 = {2^4}.5\\
 \Rightarrow ƯCLN\left( {18;80} \right) = 2\\
 \Rightarrow ƯC\left( {18;80} \right) = \left\{ {1;2} \right\}\\
b,\\
60 = {2^2}.3.5\\
84 = {2^2}.3.7\\
 \Rightarrow ƯCLN\left( {60;84} \right) = {2^2}.3 = 12\\
 \Rightarrow ƯC\left( {60;84} \right) = Ư\left( {12} \right) = \left\{ {1;2;3;4;6;12} \right\}\\
c,\\
16 = {2^4}\\
24 = {2^3}.3\\
 \Rightarrow ƯLCN\left( {16;24} \right) = {2^3} = 8\\
 \Rightarrow ƯC\left( {16;24} \right) = Ư\left( 8 \right) = \left\{ {1;2;4;8} \right\}\\
d,\\
160 = {2^5}.5\\
224 = {2^5}.7\\
 \Rightarrow ƯCLN\left( {160;224} \right) = {2^5} = 32\\
 \Rightarrow ƯC\left( {160;224} \right) = Ư\left( {32} \right) = \left\{ {1;2;4;8;16;32} \right\}
\end{array}\)
