Question

hãy tìm ƯCLN(150 và 1000) rồi tìm ƯC(150 và 1000)

Answer 1

\(150=5^2\cdot2\cdot3;1000=2^3\cdot5^3\)

=>\(ƯCLN\left(150;1000\right)=5^2\cdot2=50\)

=>\(ƯC\left(150;1000\right)=Ư\left(50\right)=\left\{1;-1;2;-2;5;-5;10;-10;25;-25;50;-50\right\}\)

Answer 2

Ta có:

=>ƯCLN(150;1000)=2.5=10

=>ƯC(150;1000)={1;2;5;10}

Answer 3

Ta có:

150=2.3.5²

1000=2³.5².7

=>ƯCLN(150;1000)=2.5=10

=>ƯC(150;1000)={-1;-2;-5;-10;1;2;5;10}
