Answer 1

Bună !

M₃={0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, ...} (3+3+3+....de n ori)

M₅={0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, ...} (5+5+5+...de n ori)

M₈={0, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, ...} (8+8+8+....de n ori)

M₁₂={0, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, ...} (12+12+12+...de n ori)

M₂={0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, ...} (2+2+2+...de n ori)

→ Mulțimea multiplilor unui număr este o mulțime infinită.
