Bài dễ thế này mà ko làm dc ngu thế 

Tự đi mà làm

FUCK YOU

a) Ư (6) = {1; 2; 3; 6}

Ư (9) = {1, 3, 9}

ƯC (6, 9) = {1; 3}.

b) Ư (7) = {1; 7}

Ư (8) = {1; 2; 4; 8}

ƯC (7, 8) = {1}.

c) ƯC (4, 6, 8) = {1, 2}.

a) Ư (6) = {1; 2; 3; 6}, Ư (9) = {1, 3, 9}, ƯC (6, 9) = {1; 3}.

b) Ư (7) = {1; 7}, Ư (8) = {1; 2; 4; 8}, ƯC (7, 8) = {1}.

c) ƯC (4, 6, 8) = {1, 2}.

a)Ư(6)={1;2;3;6}

Ư(9)={1;3;9}

Ư(6;9)={1;3}

b)Ư(7)={1;7}

Ư(8)={1;2;4;8}

ƯC(4;6;8)={1;2)

a,ƯC(6,9)=(18,36,54,72,...)

\(\text{Ư}\left(6\right)=\left\{1;2;3;6\right\}\)

\(\text{Ư}\left(9\right)=\left\{1;3;9\right\}\)

\(\text{Ư}C\left(6;9\right)=\left\{3\right\}\)

a)  Ư(6) ={1;2;3;6}    Ư(9)= {1;3;9}       ƯC(6,9) ={1;3}

k mik nha

\(B\left(-12\right)=\left\{0;\pm12;\pm24;\pm36;\pm48...\right\}\)

\(B\left(8\right)=\left\{0;\pm8;\pm16;\pm24;\pm32...\right\}\)

Vì là bội nên không có giới hạn nha!

\(Ư\left(15\right)=\left\{\pm1;\pm3;\pm5;\pm15\right\}\)

\(Ư\left(-9\right)=\left\{\pm1;\pm3;\pm9\right\}\)

\(Ư\left(4\right)=\left\{\pm1;\pm2;\pm4\right\}\)

B(-12)={0,+-12,+-24,+-48,...}

B(8)={0,+-8,+-16,+-24,...}

Ư(15)={+-1,+-3,+-5,+-15}

Ư(-9)={+-1,+-3,+-9}

Ư(4)={+-1,+-2,+-4}

Ư(4)={1,2,4}

Ư(9)={1,3,9}

Ư(8)={1,2,4,8} k cho mink

Ư(4) = ( 1;2;4 )

Ư(9) = ( 1;3;9 )

Ư(8) = ( 1;2;4;8 )

u(4) =( 1, 2, 4 )

u (9  = (1 ,3 , 9)

u (8 )=1 , 2, 4, 8)

k mình nha gửi bạn vài tấm ảnh động
