Question

uoc chung cua 24 ,84 va 180

Answer 1

12 nha nguyen vu phuong anh

Answer 2

24 = 2³.3

84 = 2².3.7

180 = 2².3².5

=> ƯCLN(24, 84, 180)= 2².3 = 12

=> ƯC(24, 84, 180)=Ư(12)={1;2;3;4;6;12}

Answer 3

Phân tích ra thừa số nguyên tố:

24 = 2³.3 ; 84 = 2².3.7 ; 180 = 2².3².5

=> UCLN(24;84;180) = 2².3 = 12 

=> UC(24;84;180) = U(12) = {1;2;3;4;6;12}
