\(a=24=2^3\cdot5\\ b=60=2^2\cdot3\cdot5\\ ƯCLN\left(a,b\right)=2^2\cdot3=12\\ ƯC\left(a,b\right)=Ư\left(12\right)=\left\{1;2;3;4;6;12\right\}\)
\(a.\)\(A=24=2^3.5\)
\(B=60=2^2.3.5\)
\(b.ƯCLN\left(a,b\right)=2^2.5=20\)
\(ƯC\left(a,b\right)=Ư_{\left(20\right)}=\left\{1;2;3;4;10;20\right\}\)
a) 24=23.3 60=22.3.5
b)ƯCLN(24,36)= 12 \(\Rightarrow\)ƯC(24,36)=Ư(12)=(1;2;3;4;6;12)
