→ Mₙ={0, n, 2n, 3n, 4n, ...}
M₁₂={0, 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, ...}
100< M₁₂< 200={108, 120, 132, 144, 156, 168, 180, 192}
12 x 9 = 108
12 x 10 = 120
12 x 11=132
12 x 12=144
12 x 13=156
12 x 14=168
12 x 15=180
12 x 16=192
M={108,120,132,144,156,168,180,192}
