How can I determine the common factors of a set of numbers?

[jayjay713]

3.5, 5.4, 8.2, 8.9, 13.6, 14.7, 17.1 22.9, 28.3, 31.8.

is there any easier way then by hand :\

thanks for any help

You could look for the Greatest Common Divisor (GCD) if you first multiply all the values by 10 in order to make them integers. There are GCD applets on the web if you do a search.

The method may be inappropriate if your values are rounded or truncated measured data values, as it will fail to find a value that is a 'divisor' within experimental error but is not an exact divisor of the given numbers.
