BC 9,12

BC 6,10

BC8,12

BC 15,20

BCNN 1,8

BCNN 36,72

BCNN60,150

BCNN 10,12,15

Answer 1

\(BC\left(9,12\right)=\left\{0;36;72;...\right\}\)

\(BC\left(6,10\right)=\left\{0;30;60;...\right\}\)

\(BC\left(8,12\right)=\left\{0;24;48;...\right\}\)

\(BC\left(15,20\right)=\left\{0;60;120;...\right\}\)

\(BCNN\left(8,1\right)=8\)

\(BCNN\left(36,72\right)=36\cdot2=72\)

\(BCNN\left(60;150\right)=300\)

\(BCNN\left(10,12,15\right)=60\)

Answer 2

B( 9 ) = { 0 ; 9 ; 18 ; 27 ; 36 ; 45 ; 54; 63 ; 72; .... }

B( 12 ) = { 0 ; 12 ; 24 ; 36 ; 48 ; 60 ; 72 ; ...}

⇒ BC( 9, 12 ) = { 0 ; 36 ; 72 ;...}

B( 6 ) = { 0 ; 6 ; 12 ; 18 ; 24 ; 30 ; 36 ; 42 ; 48 ; ..}

B ( 10 ) = { 0 ;  10 ; 20 ; 30 ; 40 ..}

⇒ BC (6,10 ) =  { 0 ; 30 ... }

B ( 8 ) = { 0 ; 8 ; 16 ; 24 ; 32 ; 40 ; 48 ; 56, ...}

( Bội của 12 đã liệt kê bên trên )

⇒ BC ( 8,12 ) = { 0 ; 24 ;  36 ; 48 ; ...}

Answer 3

$BC\left(9,12\right)=\left\{0;36;72;...\right\}$

$BC\left(6,10\right)=\left\{0;30;60;...\right\}$

$BC\left(8,12\right)=\left\{0;24;48;...\right\}$

$BC\left(15,20\right)=\left\{0;60;120;...\right\}$

$BCNN\left(8,1\right)=8$

$BCNN\left(36,72\right)=36\cdot 2=72$

$BCNN\left(60;150\right)=300$

$BCNN\left(10,12,15\right)=60$
