BCNN ( 60 ; 32 ) = 320
ƯCLN ( 120 ; 320 ; 80 ) = 40
\(60=2^2.3.5\)
\(32=2^5\)
\(BCNN\left(60;32\right)=2^5.3.5=480\)
BCNN ( 60; 32 ) = 480
Ư CLN ( 120 ; 320 ; 80 ) = 40
60=3 x 22 x5
32=25
BCNN(6O;32)=25X 5 X 3=480
120=23 x 5 x 3
320 =26 x 5
80=24 x5
UCLN(120;320;80)=23 x 5=40
hứa nha
\(120=2^3.3.5\)
\(320=2^6.5\)
\(80=2^4.5\) \(UCLN\left(120;320;80\right)=2^3.5=40\)
Nhầm sửa lại nha :
BCNN ( 60 ; 32 ) = 480
ƯCLN ( 120 ; 320 ; 80 ) = 40
