Question

BCNN(54;40)

Answer 1

Ta có: 

`54 = 2.3^3`

`40 = 2^3 . 5`

`=> BCN``N(40;54) = 2^3 . 3^3 . 5 = 1080`

Answer 2

BCNN(54;40)= 1080

Answer 3

BBNN(54; 40)

54 = 2.3³; 40 = 2³.5

BCNN(54; 40) = 2³.3³.5 = 1080

Answer 4

Ta có:

54 = 2.3³

40 = 2³.5

BCNN(54,40) = 2³.3³.5 = 1080

Vậy BCNN(54,40) = 1080.
