Question

Hãy tìm UC(12,27) , UC(6,15)   ,  UC(21,10,12)

 

Answer 1

12 = 2².3

27 = 3³

ƯCLN(12; 27) = 3

ƯC(12; 27) = Ư(3) = {1; 3}

--------

6 = 2.3

15 = 3.5

ƯCLN(6; 15) = 3

ƯC(6; 15) = Ư(3) = {1; 3}

--------

21 = 3.7

10 = 2.5

12 = 2².3

ƯCLN(21; 10; 12) = 1

ƯC(21; 10; 12) = Ư(1) = {1}
