L.C.D. = 481/2____3/4__11/16___2/3___1/8___5/12
24/48_36/48_33/48__32/48__6/48__20/48

1/2 , 3/4 ,11/16 , 2/3 , 1/8 , 5/12
= 24/48, 36/48, 33/48, 32/48, 6/48, 20/48
lcd = (3 x 11 x 12 x 4 x 2 x 4 x 5)/48
= 11 x 12 x 2 x 5
= 1320
= 24/48, 36/48, 33/48, 32/48, 6/48, 20/48
lcd = (3 x 11 x 12 x 4 x 2 x 4 x 5)/48
= 11 x 12 x 2 x 5
= 1320

Is this one group? If so, the LCD would be 48.
That would make them
24/48, 36/48, 33/48, 32/48, 6/48, 20/48
That would make them
24/48, 36/48, 33/48, 32/48, 6/48, 20/48
