m nha

trả lời:

a.ƯCLN(16,24)=8

b.ƯCLN(180,234)=18

C. ƯCLN(6-,90,135)=15

Học tốt!!!!!!!!

ƯCLN(16,24)={8}

CLN(180,234)={18}

CLN(60,90,135)={15}

a)ƯCLN(16;24)=8

chưa học ahihi :))

a, 16= 2⁴

24= 2³.3

\(\Rightarrow\)ƯCLN (16; 24)= 2³= 8

\(\Rightarrow\)ƯC (16; 24)= Ư (8)= {1;2;4;8}

b, 180= 2².3².55

234= 2.3³.13

\(\Rightarrow\)ƯCLN (180; 234)= 2.3²= 18

\(\Rightarrow\)ƯC (180; 234)= Ư (18)= {1;2;3;6;9;18}

c, 60= 2².3.5

90= 3².2.5

135= 3³.5

\(\Rightarrow\)ƯCLN (60;90;135)= 3.5= 15

​​​\(\Rightarrow\)ƯC (60;90;135)= Ư (15)= {1;3;5;15}​

a) Ta có: 16=4^2=2^4

24=3.8=3.2^3

​ƯCLN(16,24)=2^3=8

Ư​C(16,24)=Ư(8)={1,2,4,8}

b) Ta có: 180=2^2.3^2.5

243=2.3^2.13

60=2^2.3.5

90=2.3^2.5

135=3^3.5

​ƯCLN(234,180,60,90,135)=3

Ư​C(234,180,60,90,135)=Ư(3)={1,3}

a) ƯCLN là 8             b) ƯCLN là 3                                                                

ngu thế! Dễ thế mà ko biết làm!

a. ưcln(16,24)=8

=> ưc(16,24)=ư(8)={1;2;4;8}

b,c tương tự

Bài 1:

60= 2².3.5 ; 88 = 2³.11

ƯCLN(60;88)= 2² = 4

ƯC(60;88)=Ư(4)={1;2;4}

Bài 2:

24= 2³.3 ; 30=2.3.5 ; 40 = 2³.5

BCNN(24;30;40)=2³.3.5= 120

BC(24;30;40)=B(120)={0;120;240;360;...}

a: UCLN(24;40)=8

UC(24;40)={1;2;4;8}

b: UCLN(42;98)=14

UC(42;98)={1;2;7;14}
