Question

Answer 1

\(48=2^4\cdot3;168=2^3\cdot3\cdot7;360=2^3\cdot3^2\cdot5\)

=>\(ƯCLN\left(48;168;360\right)=2^3\cdot3=24\)

=>\(ƯC\left(48;168;360\right)=Ư\left(24\right)=\left\{1;2;3;4;6;8;12;24\right\}\)

Chọn D

Answer 2

`#3107.101107`

Ta có:

`48 = 2^4 * 3`

`168 = 2^3 * 3 * 7`

`360 = 2^3 * 3^2 * 5`

`=>` ƯCLN`(48; 168; 360) = 2^3 * 3 = 24`

`=>` ƯC`(48; 168; 360) = {1; 2; 3; 4; 6; 8; 12; 24}.`

`=>` Chọn đáp án D.
