Question

Determinati c.m.m.d.c si c.m.m.m.c.-ul numerelor 350 si 420.

Answer 1

350=2*5²*7

420=2²*3*5*7

(350,420)=2*5*7=70

[350,420]=2²*3*5²*7=2100

Answer 2

350=2×5^2×7

420=2^2×5×3×7

c.m.m.d.c.
(350; 420)=2•5•7=70
$(350 \: si \: 420) = 2 \times 5 \times 7 = 70$

c.m.m.m.c.
[350; 420]=2^2•5^2•3•7=2100
$|350 \: si \: 420 \: | = {2}^{2} \times {5}^{2} \times 3 \times 7 = 2100$

Așa trebuie făcut după ce descompui numerele.
