27 = 33
100 = 102
BCNN(27,100) = 33 . 102 = 2700
27 = 3^3
100 = 2^2 . 5^2
=> BCNN ( 27, 100 ) = 3^3 . 2^2 . 5^2 = 2700
Vậy,..........
Hok tốt
Ta có :
27 = 33
100 = 22 x 52
=> BCNN( 27; 100 ) = 22 x 33 x 52 = 2700
Vậy BCNN( 27; 100 ) = 2700
BCNN ( 27 ) = 1,3,9,27.
BCNN ( 100 ) = 1, 2, 4,5,10,20,25, 50, 100.
=> BCNN ( 27,100 ) = 1
Ta có :
27 = 33
100 = 22 . 5 2
BCNN(27;100) = 22 . 33 . 52 = 2700
Vậy BCNN(27;100) = 2700
Tk mik nha^^
Ta có 27=33
100=22.52
BCNN (27;100) = 27.100=2700
