Question

BCNN(12,18,30)

Answer 1

BCNN( 12,18,30)

=> 12=2^2 x 3

18=2 x 3^3

30=2x3x5

=>BCNN( 12 ,18,30)=2^2 x 3^3 x 5=180

=>BCNN(12,18,30)= 180

Answer 2

12=2^2.3

18=2.3^3

30=2.3.5

=> BCNN(12,18,30)=180

Answer 3

Ta có:

12 = 2²x3

18 = 2x3²

30 = 2x3x5

=> BCNN(12;18;30) = 2²x3²x5 = 4x9x5 = 180
