(6,8)=2 [6,8]=24 (8,10)=2 [8,10]=40 (9,16)=1 [9,16]=144 (5,8)=1 [5,8]=40 (10,11)=1 [10,11]=110 (32,48)=16 [32,48]=96 [18,24]=72 [57,19]=57 [28,35]=140 [36,48]=144 [3,4,6]=12
小窍门:8/6=1......2 6/2=3......0 所以(6,8)=2
48/32=1......16 32/16=2......0 所以(48,32)=16
8×6/2=24 [6,8]=24 32×48/16=96 [32,48]=96
ab/(a,b)=[a,b]
