Răspuns:

Explicație pas cu pas:

a) 18 = 2·3²  ; 24 = 2³·3

cmmdc = 2·3 = 6 ; cmmmc = 2³·3² = 72

----------------------------------------------------------

b) 6 = 2·3 ; 12 = 3·2² ; 8 = 2³

cmmdc = 2 ; cmmmc = 2³·3 = 24

---------------------------------------------------------

c) 8 = 2³ ; 9 = 3² ; 18 = 2·3²

cmmdc = 1 ; cmmmc = 2³·3² = 72

----------------------------------------------------------

d) 15 = 3·5 ; 35 = 5·7

cmmdc = 5 ; cmmmc = 3·5·7 = 105

----------------------------------------------------------

e) 64 = 2⁶ ; 81 = 3⁴

cmmdc = 1 ; cmmmc = 2⁶·3⁴ = 5184

----------------------------------------------------------

f) 4 = 2² ; 8 = 2³ ; 6 = 2·3

cmmdc = 2 ; cmmmc = 2³·3 = 24

----------------------------------------------------------

g) 12 = 2²·3 ; 28 = 2²·7

cmmdc = 2² = 4 ; cmmmc = 2²·3·7 = 84

----------------------------------------------------------

h) 16 = 2⁴ ; 24 = 2³·3 ; 40 = 2³·5

cmmdc = 2³ = 8 ; cmmmc = 2⁴·3·5 = 240
