Uses Euclid's method of recursively computing the GCF (the GCF of two numbers is the same as the GCF of the smaller and the remainder (modula) of the larger divided by the smaller; and by definition, the GCF of any number and 0 is the number)

Note that the lowest common multiple of two numbers is their product divided by their GCF. In otherwords:
LCM(A, B) = A * B / GCF(A,B)

This is my Custom Function and I want to edit it


This will be my first attenot to impliment of a Custom Fucntion with in FileMaker. I nearly need step by step instuctions as to how to set one up. The GCF Function is one that I need, but I also seek the Greatest Common Divisor (GCD) so I can constuct ratios exressions (34:1).

Might you be able to aide me?
