Question

ƯCLN(24;36;120)

Answer 1

\(\left[{}\begin{matrix}24=2^3.3\\36=2^2.3^2\\120=3.5.2^3\end{matrix}\right.\Rightarrow UWCLN\left(24;36;120\right)=2^2.3=12\)

Answer 2

Ta có :

\(24=2^3.3\)

\(36=2^2.3^2\)

\(120=2^3.3.5\)

\(\RightarrowƯCLN_{\left(24;36;120\right)}=2^2.3=12\)

Answer 3

Ta có:

24 = 12. 2

36 = 12 . 3

120 = 12 . 10

Ta có bảng:

12	2
12	3
12	10

\(\Rightarrow\) ƯCLN = 12

Answer 4

24=2³ . 3

36=2² . 3²

120 = 3.5.2³

=> ƯCLN(24;;36;120)=2².3
