Hello all,

I am trying to wrap my mind around a way to solve a problem and could use some advice or help. The best I can do is form this into a word problem.

So, The problem is this:

I need to find points that coincide with each other.

For example, I have 2 wooden blocks that each have a different length.

Block one is 3 inches long, and block 2 is 8 inches long.

point 0 is the same for both blocks. The next point these blocks have a common break point is 24, then 48, and so on.

My problem is that I have several blocks of different lengths, and I need to identify these common break points in relation to each other.

In other words I am not looking for a common break point for all of them. Just the points where these blocks line up with the others break points, wherever they may occur.

For example with three blocks. Lengths 3 inches (red block), 8 inches ( blue block), and 10 inches (yellow block).

common break points for red and blue blocks would be 24, 48.. etc.

Common break point between red and yellow blocks are 30, 60...etc.

common break point between yellow and blue blocks are 80, 160...etc.

In actuality I would be comparing about 8 blocks of different lengths, and would like to make a spreadsheet to find these points where the ends of the blocks line up.

Can anyone out there think of an easy way to chart this type of information suitable for making a spreadsheet?

Regards,

Alex
