Có 16 = 2 4 ; 24 = 2 3 . 3 nên UCLN(16,24) = 2 3 = 8
Vậy UC(16,24) = {1;2;4;8}
b, Có 180 = 2 3 . 3 2 . 5 ; 234 = 2 . 3 2 . 13 nên UCLN(180,234) = 2.3 = 6
Vậy UC(180,234) = {1;2;3;6}
c, Có 60 = 2 2 . 3 . 5 ; 90 = 2 . 3 2 . 5 ; 135 = 3 3 . 5 nên UCLN(60,90,135) = 3.5 = 15
Vậy UC(60,90,135) = {1;3;5;15}
a)
Ta có : 16 = 24
24 = 23 x 3
=> UCLN (16,24) = 23 = 8
=> ƯC (16,24) = Ư(8) = {1;2;4;8}
b)
Ta có : 180 = 22 x 32 x 5
234 = 2 x 32 x 13
=> UCLN (180,234) = 2 x 32 = 18
=> ƯC (180,234) = Ư(18) = {1;2;3;6;9;18}
c)
Ta có : 60 = 22 x 3 x 5
90 = 2 x 32 x 5
135 = 33 x 5
=> UCLN (60,90,135) = 3 x 5 = 15
=> ƯC (60,90,135) = Ư(15) = {1;3;5;15}
Ta có : 16=24 24=23.3
UCLN (16,24)=23=8
=> UC(16,24,)=(1,2,4,8)
Tich nha
Ta có:16=24 24=23x3
ƯCLN(16,24)=23=8
=> ƯC(16,24)=(1,2,4,8)
Ta có: 180=22x32x5 234=2x32x13
ƯCLN(180,234)=2x32=18
=> ƯC(60,90,135)=180,234)=(1,2,3,6,9,18)
Ta có:60=22x3x5 90=2x32x5 135=33x5
ƯCLN(60,90,135)=3x5=15
=> ƯC(60,90,135)=(1,3,5,15)
Đây nha bạn.
Chúc bạn học tốt!
a) Ta có: 16=4^2=2^4

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
