Question

UCLN(180;120;90)

Answer 1

30 đó bn

k mik nhé

tks bạn

Answer 2

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

Answer 3

180 = 2² . 3² . 5

120 = 2³ . 3 . 5

90 = 2 . 3² . 5

ƯCLN(180,120,90) = 2 . 3 . 5 = 30

Answer 4

180 = 2² . 3² . 5

120 = 2³ . 3 .5 

90  = 2.3²

ƯCLN ( 180 , 120 , 90 ) = 2 .3 = 6

Answer 5

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

Answer 6

ƯCLN (180,120,90)

Ta có :180= 2^2x3^2x5

120=2^3x3x5

90=2x3^2x5

ƯCLN (180,120,90)=2x3x5=30

Answer 7

30

Answer 8

Ta có:

180 = 2².3².5

120 = 2³.3.5

 90  = 2.3².5

ƯCLN (180,120,90) = 2.3.5 = 30
