Question

BCNN (42,72,180) là

Answer 1

\(42=2.3.7\\ 72=2^3.3^2\\ 180=2^2.3^2.5\)

 

→BCNN (42,72,180)=\(2^3.3^2.5.7=2520\)

 

 

 

Answer 2

42 = 2 . 3 . 7

72 = 2³ . 3²

180 = 2² . 3² . 5

BCNN(42, 72, 180) = 2³ . 3² . 5 . 7 = 2520

Answer 3

\(42 = 2.3.7 \)

\(72=2^3.3^2\)

\(180=2^2.3^2.5\)

\(=>BCNN(42,72,180)=\)\(2^3.3^2.5.7=2520\)
