i: \(18=3^2\cdot2\)
=>\(Ư\left(18\right)=\left\{1;-1;2;-2;3;-3;6;-6;9;-9;18;-18\right\}\)
k: \(24=2^3\cdot3\)
=>\(Ư\left(-24\right)=Ư\left(24\right)=\left\{1;-1;2;-2;3;-3;4;-4;6;-6;8;-8;12;-12;24;-24\right\}\)
l: \(12=2^2\cdot3\)
=>\(Ư\left(12\right)=Ư\left(-12\right)=\left\{1;-1;2;-2;3;-3;4;-4;6;-6;12;-12\right\}\)
m: \(27=3^3\)
=>\(Ư\left(27\right)=\left\{1;-1;3;-3;9;-9;27;-27\right\}\)

Ư(10) = { 1 ; 2 ; 5 ; 10 }
B(10) = { 0 ; 10 ; 20 ; 30 ....}
Trả lời :
\( Ư\left(24\right)=\left\{1;2;3;4;6;8;12;24\right\}\)
Hk tốt
Ư(24) gồm: 1;2;3;4;6;8;12;24 ok
