72的倍數

倍數:
72 x 1 = 72
72 x 2 = 144
72 x 3 = 216
72 x 4 = 288
72 x 5 = 360
72 x 6 = 432
72 x 7 = 504
72 x 8 = 576
72 x 9 = 738
72 x 10 = 720
72 x 11 = 792
72 x 12 = 864
72 x 13 = 936
72 x 14 = 1008
72 x 15 = 1080
72 x 16 = 1152
72 x 17 = 1224
72 x 18 = 1296
72 x 19 = 1368
72 x 20 = 1440
72 x 21 = 1512
72 x 22 = 1584
72 x 23 = 1656
72 x 24 = 1728
72 x 25 = 1800
等等....
倍數係冇限個...寫唔晒...

因數:
1X72=72
2X36=72
3X24=72
4X18=72
6X12=72
8X9=72
所以1,2,3,4,6,7,8,9,12,18,24,36,72係72既因數
(希望幫到你la)

72x1=72
72x2=144
72x3=216
72x4=288
72x5=360
72x6=432
72x7=504
72x8=576
72x9=648
72x10=720



其實,所有數的倍還有很多,最多有無限

72,144,216,288,360,432,504,576,648,720

72 x 1 = 72

72 x 6 = 432
72 x 7 = 504
72 x 8 = 576
72 x 9 = 738
72 x 10 = 720
72 x 11 = 792
72 x 12 = 864
72 x 13 = 936

72 x 15 = 1080
72 x 16 = 1152
72 x 17 = 1224
72 x 18 = 1296
72 x 19 = 1368
72 x 20 = 1440
72 x 21 = 1512
72 x 22 = 1584
72 x 23 = 1656
72 x 24 = 1728
72 x 25 = 1800
72 x 26 = 1872
72 x 27 = 1944
72 x 28 = 2016
72 x 29 = 2088
72 x 30 = 2160

72 = 1 x 7272 = 2 x 3672 = 3 x 2472 = 4 x 1872 = 6 x 1272 = 8 x 9so 72的因數有1,2,3,4,6,8,9,12,18,24,36,7272可寫成的質因數連乘式: 8 x 9 = 2 x 2 x 2 x 2 x 3 x 3 = 2^4 x 3²

72,144,216,288,360,432,504
無限個

72*1=72
72*2=144
72*3=216
72*4=288
72*5=360
72*6=432
72*7=504
72*8=576
72*9=648
72*10=720
其實72o既倍數有無限個,因為數字可以無限大!

而因數就有12個:(1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72)因為72=1*722*363*244*186*128*9

2x2x2x3x3=72
因此, 72的倍數是2 和 3

2倍就144
3倍就216
4倍就288
多一倍就加72~如此濾推!!無限的
