LCM : 9 x 100 x 49
can be rephrased as 9 x
100 x 7 x 7 -> 700 is a valid factor
can be rephrased as
9 x 100 x 49 -> 900 is a valid factor
can be rephrased as 3 x
3 x 100 x 7 x 7 -> 2100 is a valid factor
can be rephrased as 9 x
100 x 49 -> 4900 is a valid factor
can't be rephrased similarly for 600 , hence 600 is the answer
