Question

BCNN(40,60,120) là

Answer 1

BCNN(40,60,120) là 120

Answer 2

=120

Answer 3

BCNN(40; 60; 120) 

Ta có: 

40 = 2³ . 5

60 = 2² . 3 . 5

120 = 2³ . 3 . 5

=> BCNN(40; 60; 120) = 2³ . 3 . 5 = 120.

Answer 4

\(40=2^3.5\)

\(60=2^2.3.5\)

\(120=2^3.3.5\)

\(BCNN\left(40;60;120\right)=2^3.3.5=120\)

Answer 5

\(40 = 2 ^3 .5\)

\(60 = 2 ^2 .3 .5\)

\(120 = 2^3 . 3 . 5\)

\(=>BCNN(40;60;120)=2^3.3.5=120\)
