Question

ƯCLN(12,9,15,3)=?

 

Answer 1

\(12=2^2\cdot3\)

\(9=3^2\)

\(15=3\cdot5\)

\(3=3\)

`=>`\(ƯCLN\left(12;9;15;3\right)=3\)

 

Answer 2

`12=2^2 . 3`

`9=3^2`

`15=3.5`

`3=3`

`=>ƯCLN(12,9,15,3)=3`

Answer 3

ƯCLN(12;9;15;3)=3

Answer 4

ta có :

 `12 = 2^2 xx 3`

 `9 = 3^2`

 `15 = `3 xx 5

 `3 = 3`

=>` ƯCLLN(12 ; 9 ; 15; 3) = 3`
