Ta có :
16=2^4
34=2.17
240=2^4.3.5
=>BCNN(16;34;240)=2^4.17.3.5=4080
Vay BCNN(16;34;240)=4080
dung thi k nhe neu sai bao mik thi mik xem lai
OK tks
16 = 24
34 = 2 . 17
240 = 24. 3 . 5
BCNN ( 16;34;240 ) = 24, 3.5.17 = 4080
Đáp án chính là 4080
ta co:16=2^4
34=2.17
240=2^4.3.5
suy ra BCNN cua (16,34,240)=2^4.4.3.5.17=16 320
16 = 2 ^ 4 34 = 2 . 17 240 = 2 ^ 4 . 3 . 5
BCNN ( 16 , 34 , 120 ) = 2 ^ 4 . 17 . 3 . 5 = 4080
