Question

Calculati (30,48,72):[115,46,529] dau coronița la fetiță

Answer 1

(30,48,72):[115,46,529]

(30,48,72)= cmmdc(30,48,72)

30=2×15=2×3×5

48=6×8=2×3×2³

72=2×2×3×2×3=2³×3²

cmmdc(30,48,72) = (30,48,72) = 2×3=6

cmmmc(115,46,529)=?

115=5×23

46=2×23

529=23²

cmmmc(115,46,529)=[115,46,529]=2×5×23²=5290

6:5290=3/2645

(30,48,72):[115,46,529] =6:5290=3:2645
