Question

tìm UWCLN va tìm ước chung của nó:
                             72 và 60

Answer 1

\(ƯCLN(60;72)\)

\(60= 2^2 x3x5\)

\(72= 2^3x3^2 \)

\(=> ƯCLN (60;72) = 2^2x3=12 \)

 

Answer 2

`72 = 2^3 . 3^2`

`60 = 2^2 . 3 . 5`

`=> ƯCLN(60,72) = 2^2 . 3 = 12`

________________________________________

`72 = ∈ { 1,2,3,4,6,8,9,12,18,24}`

`60 = ∈ { 1,2,3,4,5,6,10,12,15,20}`

`=> ƯCLN (722,60) = { 1,2,3,4,6,12}`

Answer 3

ƯCLN(60;72)ƯCLN(60;72)

$60={}^{}x3x5$

$72={}^{}x{}^{}$

=>ƯCLN(60;72)=22x3=12
