ta có: 128 = 27
240= 24.3.5
=>ƯCLN(128,240)=24=16
=>ƯC(128,240)=Ư(16)={1;2;4;8;16}
vậy ƯC(128,240)={1;2;4;8;16}
tic cho mình nha
\(ƯC\left(128,240\right)\)
\(128=2^7\)
\(240=2^4.3.5\)
\(ƯCLN(128,240) =2^4 = 16\)
\(ƯC\left(128;240\right)=ƯC\left(16\right)=\left\{1;2;4;8;16\right\}\)
Ta cs : 128 = 27 UCLN (128,240)=24=16
240 = 24.3.5
suy ra UC của (128,240) = Ư(16)=(1;2;4;8;16)
