Question

Answer 1

a) \(40=2^3.5;24=2^3.3=>ƯCLN\left(40;24\right)=2^3=8\)
\(=>ƯC\left(40;24\right)=\left\{2;4;8\right\}\)
b) \(12=2^3.3;52=2^2.13=>ƯCLN\left(12;52\right)=2^2=4\)
\(=>ƯC\left(12;52\right)=\left\{2;4\right\}\)
c) \(36=2^2.3^2;990=2.3^2.5.11=>ƯCLN=2.3^2\)
\(=>ƯC\left(36;990\right)=\left\{2;3;3^2;2\right\}\)
d) \(54=2.3^3;36=2^2.3^2=>UWCLN=2.3^2\)
\(=>ƯC=\left\{2;3;3^2;2.3^2\right\}\)
