Ta có:
180=2^2.3^2.5
120=2^3.3.5
90=2.3^2.5
=>UCLN(180;120;90)=2.3.5=30
180 = 22 . 32 . 5
120 = 23 . 3 . 5
90 = 2 . 32 . 5
ƯCLN(180,120,90) = 2 . 3 . 5 = 30
180 = 22 . 32 . 5
120 = 23 . 3 .5
90 = 2.32
ƯCLN ( 180 , 120 , 90 ) = 2 .3 = 6
ta có: 180=\(2^2.3^2.5\) \(120=2^3.3.5\) \(90=2.3^2.5\)
\(\Rightarrow\)ƯCLN(180,120,90)= 2.3.5=30
ƯCLN (180,120,90)
Ta có :180= 2^2x3^2x5
120=2^3x3x5
90=2x3^2x5
ƯCLN (180,120,90)=2x3x5=30
Ta có:
180 = 22.32.5
120 = 23.3.5
90 = 2.32.5
ƯCLN (180,120,90) = 2.3.5 = 30
