The six angles measures are 2x, 3x, 4x, 5x, 6x and 7x,  where x is their common measure.


The sum of interior angles of any n-sided polygon is  (n-2)*180 degrees, therefore


    2x + 3x + 4x + 5x + 6x + 7x = 4*180,    or

    27x = 720

    x =  =  degrees.


The greatest angle measure is  7 times  degrees,  or  degrees =  degrees.

Solved.
