Bg :
\(12=2^2.3\)
\(30=2.3.5\)
\(\RightarrowƯCLN\left(12,30\right)=2.3=6\)
P/s : Hok tốt ~
ta có:12=2^2*3
30=2*3*5
=>ƯCLN(12,30)=2*3=6
ƯCLN(12,30)=6
k nha
Học tốt
^_^
Theo bài ra ta có:
12 = 22 x 3
30 = 2 x 3 x 5
Suy ra UCLN ( 12, 30 ) = 2 x 3 = 6
Vậy UCLN ( 12, 30 ) = 6
ta có:
12=2^2 . 3
30=2 . 3 . 5
suy ra UCLN (12:30)=2 . 3 = 6
nho viet dau suy ra la dau nhe
ta co
12=2^2.3
30=2 .3.5
-) UCLN(12, 30)=2.3= 6
