Answer 1

[Nguyễn Lê Phước Thịnh]

a: \(Ư\left(16\right)=\left\{1;2;4;8;16\right\}\)

\(Ư\left(24\right)=\left\{1;2;3;4;6;8;12;24\right\}\)

\(ƯC\left(16;24\right)=\left\{1;2;4;8\right\}\)

b: \(Ư\left(20\right)=\left\{1;2;4;5;10;20\right\}\)

\(Ư\left(32\right)=\left\{1;2;4;8;16;32\right\}\)

\(ƯC\left(20;32\right)=\left\{1;2;4\right\}\)
