Question

Tim cac UC ( 144, 192, 240 ) ma co 2 chu so

Answer 1

144 = 2⁴ . 3²

192 = 2⁶ . 3

240 = 2⁴ . 3 . 5

\(\Rightarrow\)ƯCLN ( 144,192,240 ) = 2⁴ . 3 = 48

\(\Rightarrow\)ƯC ( 144,192,240 ) = \(\left\{12;16;24;48\right\}\)

Answer 2

Ta có :

144 = 2⁴ . 3²

192 = 3 . 2⁶

240 = 2⁴ . 3 . 5

=> ƯCLN ( 144,192,240 ) = 48

=> Ư ( 48 ) = { 1 ; 2 ; 3 ; 4 ; 6 ; 8 ; 12 ; 24 ; 48 }

Vậy các ƯC ( 144,192,240 ) mà có hai chữ số là 12 , 24 , 48

Answer 3

Ta có:

144 = 2⁴ . 3²

192 = 3 . 2⁶

240 = 2⁴ . 3 . 5

=> ƯCLN (144, 192, 240) 

=> Ư(48) = {1;2;3;4;6;8;12;24;48}

=> ƯC(144,192,240) = {12;24;48}

Answer 4

UC(114;196;240)=12
