Câu hỏi: Viết các tập hợp sau:a) \(U(6);\,U(20);\,UC(6,20)\)b) \(UC(8;\,32;\,64).\)

A a) \({\rm{UC(6;\,20) = }}\left\{ {{\rm{1;\,2}}} \right\}\)

b) \(\left\{ {32;\,64} \right\} \subset {\rm{B(8)}} \\ \Rightarrow UC(8;\,32;\,64) = U(8) = \left\{ {{\rm{1;\,2;\,4;\,8}}} \right\}\)

B a) \({\rm{UC(6;\,20) = }}\left\{ {{\rm{1;\,4}}} \right\}\)

b) \(\left\{ {32;\,64} \right\} \subset {\rm{B(8)}} \\ \Rightarrow UC(8;\,32;\,64) = U(8) = \left\{ {{\rm{1;\,2;\,8}}} \right\}\)

C a) \({\rm{UC(6;\,20) = }}\left\{ {{\rm{0;\,2}}} \right\}\)

b) \(\left\{ {32;\,64} \right\} \subset {\rm{B(8)}} \\ \Rightarrow UC(8;\,32;\,64) = U(8) = \left\{ {{\rm{1;\,2;\,4}}} \right\}\)

D a) \({\rm{UC(6;\,20) = }}\left\{ {{\rm{1;\,4}}} \right\}\)

b) \(\left\{ {32;\,64} \right\} \subset {\rm{B(8)}} \\ \Rightarrow UC(8;\,32;\,64) = U(8) = \left\{ {{\rm{4;\,8}}} \right\}\)
