\(150=5^2\cdot2\cdot3;1000=2^3\cdot5^3\)
=>\(ƯCLN\left(150;1000\right)=5^2\cdot2=50\)
=>\(ƯC\left(150;1000\right)=Ư\left(50\right)=\left\{1;-1;2;-2;5;-5;10;-10;25;-25;50;-50\right\}\)

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
\(ƯC\left(128,240\right)\)
\(128=2^7\)
\(240=2^4.3.5\)
\(ƯCLN(128,240) =2^4 = 16\)
\(ƯC\left(128;240\right)=ƯC\left(16\right)=\left\{1;2;4;8;16\right\}\)

1.Ta có:
Ư(10)={1;2;5;10}.
Ư(20)={1;2;4;5;10;20}.
=> Ư(10;20)={1;2;5;10}
Cái dấu ^ là gì rồi tôi giải tiếp cho

\(36=2^2\cdot3^2\\ 120=2^3\cdot3\cdot5\\ ƯCLN\left(36,120\right)=2^2\cdot3=12\\ ƯC\left(36,120\right)=Ư\left(12\right)=\left\{...\right\}\)
Ta có: 36= 2^2. 3^2
120= 2^3. 3.5
=> ƯCLN( 36; 120)- 2^2. 3= 12
=> ƯC(36;120) = Ư(12) = { 1; 2; 3; 4; 6; 12}

Ư(80)={1;80;2;40;4;20;10;8;5;16}
Ư(126)={1;126;2;63;3;19;14}
128 = 27
1000 = 23.25
=> ƯCLN(128; 1000) = 23 = 8
=> ƯC(128; 1000) = Ư(8)
=> ƯC(128; 1000) = {1; 2; 4; 8}
