4)72,350
DAU COROANA

Answer 1

1)

600 = 2³×3×5²

130000 = 2⁴×5⁴×13

cmmmc = 2⁴×3×5⁴×13 = 390000

cmmdc = 2³×5² = 200

2)

250 = 2×5³

450 = 2×3²×5²

cmmmc = 2×3²×5³ = 2250

cmmdc = 2×5² = 50

3)

12000 = 2⁵×3×5³

4800 = 2⁶×3×5²

cmmmc = 2⁶×3×5³ = 24000

cmmdc = 2⁵×3×5² = 2400

4)

72 = 2³×3²

350 = 2×5²×7

cmmmc = 2³×3²×5²×7 = 12600

cmmdc = 2
