Question

Tìm ƯCLN(60,72)

Tìm BCNN(60,72)

Answer 1

Tìm ƯCLN(60,72)

Ta có: 2² . 3 . 5

2³ . 3²

=> ƯCLN(60,72) = 2² . 3 = 12

Tìm BCNN(60,72)

Ta có: 72 = 2³.3².

96 = 3.2⁵.

=> BCNN (72, 96)=2⁵ . 3²= 32 . 9 = 288.

Answer 2

tìm ƯCLN (60;72)

ta có:60=2² .3.5

72=2³.3²

ƯCLN(60;72)=2².3=12

tìm BCNN(60;72)

ta có:60=2².3.5

72=2³.3²

^BCNN(60;72)=2^3.3².5=60

Answer 3

60 = 3.2².5

72=2³.3²

ƯCLN ( 60,72) = 3.2²=12

BCNN ( 60,72) = 2³ . 3² .5=360

Answer 4

60 = 2² . 3 . 5

72 = 2³ . 3²

=> UCLN (60;72) = 2² . 3 = 12

=> BCNN (60;72) = 2³ . 3².5 =360
