Ta có:
84 = 22 x 3 x 7
216 = 23 x 33
168 = 23 x 3 x 7
=> UCLN ( 84; 216; 168 ) = 22 x 3 = 12
=> ƯC ( 84; 216; 168 ) = { 1; 2; 3; 4; 6; 12 }
TA CÓ : 84 = 2 MŨ 2 .3.7
216=2 MŨ 3 . 3 MŨ 3
168=2 MŨ 3 .3 .7
ƯLCN ( 84 , 216 , 168 ) = 2 MŨ 2 .3 = 12
ƯC ( 84,216,168) = Ư ( 12) = 1 ; 2 ; 3;4;6;12
84 = 22 . 3 . 7
216 = 23 . 33
168 = 23 . 3 . 7
ƯCLN ( 84 ; 216 ; 168 ) = 22 . 3 = 12
ƯC ( 84 ; 216 ; 168 ) = { 1 ; 2 ; 3 ; 4 ; 6 ; 12 }
Nhớ k cho mình nha :3 :)) :D
ƯCLN (84;216;168)
84=22.3.7
216=23.33
168=23.3.7
ƯLCN (84;216;168)=22.3=12
ƯCLN (84;216;168)=ƯC(12)=(1;2;3;4;6;12)
