Use Excel's Combin formula eg

=COMBIN(25,6) = 177100

=COMBIN(30,6) = 593775

=COMBIN(40,6) = 3838380

=COMBIN(45,6) = 8145060

Here's the way you figure it.  You start at the high number which is 45 and count back six numbers because it is a 6 ball drawing.  You multiply.  45x44x43x42x41x40.  You get the figure, 5864443200.  Now since you are trying to match the 6 balls, you start from the other end.  1x2x3x4x5x6.  You get 720.  Divide 720 into 5864443200 and you arrive at the 8145060 that Datenda posted.
