Answer 1

Salut!

a)mai intai descompunem numerele in factori primi

300=2^2 x 3 x 5^2

216=2^3 x 3^3

cmmdc (300; 216) = 2^2 × 3=12

b)45 = 3^2 × 5

72 = 2^3 × 3^2

cmmdc (45; 72) = 3^2=9

c) 112 = 2^4 × 7

252 = 2^2 × 3^2 × 7

cmmdc (112; 252) = 2^2 × 7=28

d) 90 = 2 × 3^2 × 5

300 = 2^2 × 3 × 5^2

cmmdc (90; 300) = 2 × 3 × 5=30

e) 1.890 = 2 × 3^3 × 5 × 7

2.268 = 2^2 × 3^4 × 7

cmmdc (1.890; 2.268) = 2 × 33 × 7=462

Sper ca te-am ajutat!
