Ta có :
36 = 2² . 3²
90 = 2 . 3² . 5
Do đó , BCNN ( 36 , 90 ) = 2² . 3² . 5 = 180
⇒ BC ( 36 , 90 ) = B ( 180 ) = { 0 ; 180 ; 360 ; 540 ; 720 ;…}
Vậy BC ( 36 , 90 ) = { 0 ; 180 ; 360 ; 540 ; 720 ;…}
Giải đáp:
$\text{BC(36,90)}$
$\text{Ta có:}$
$\text{36=2².3²}$
$\text{90=2.3².5}$
$\text{⇒BCNN(36,90)=2².3².5=180}$
$\text{⇒BC(36,90)={0;180;360;540;………}}$
$\text{Vậy BC(36,90)={0;180;360;540;…….}}$
