210 = 2.3.5.7
150 = 2.3.5 2
< = > UCLN﴾210 ; 150﴿ = 2.3.5 = 30
210 = 2.3.5.7
150 = 2.3.5 2
< = > UCLN﴾210 ; 150﴿ = 2.3.5 = 30
ƯCLN(210;150)=
210=2.3.5.7
150=2.3.52
ƯCLN(210;150)=2.3.5=30
Vậy ƯCLN(210;150)=30
tớ đầu tiên
210 = 2 . 3 . 5 . 7
150 = 2 . 3 . 5 . 2
< = > UCLN ( 210 : 150 ) = 2 . 3 . 5 = 30
210 = 2.3.5.7
150 = 2.3.5 2
< = > UCLN﴾210 ; 150﴿ = 2.3.5 = 30
210 = 2.3.5.7
150=150=2.3.5.7
< = >UCLN(210 : 150)=2.3.5=30
