AI NHANH NHẤT MÌNH TICK

Answer 1

Ta có :
20 = 2². 5
25 = 5²
20 = 3 . 2 . 5
=> BCNN (10,25,30)  = 2². 3 . 5² = 300

Answer 2

Ta có:

+) 20 = 2^2.5

+) 25 = 5^2

+) 30 = 3.2.5

BCNN (20,25,30) = 2^2 . 3 . 5^2 = 300

Answer 3

20 = 2.2.5 

25 = 5.5

30 = 2.3.5

BCNN (20;25;30)= 2.3.5 = 30

Answer 4

20 = 2² x 5

25 = 5²

30 = 2 x 3 x 5

BCNN ( 20 , 25, 30 ) = 2² x 5² x 3 = 300
