RE: find the lowest common denominator
I'm not sure there is a buildin function providing the lowest common denominator.
So here is a small program doing that: Code: EXPORT LCD(N,M)

In CAS, it works on integers of any length. lcm(12,18) > 36 1/12+1/18 > 5/36 It also works on polynomials, not just integers. <0ΙΈ0> Joe

RE: find the lowest common denominator
Good point, I misunderstood the request as beeing for the lowest common divisor.

RE: find the lowest common denominator
I'm getting to go through this basic math with my kids now.
I think the least common divisor can be found with the "1" function. ;^) On the 50g, this was actually function of sort, at least a token so that this commonly used number parsed faster than a number literal. Don't know that they have done the same with the Prime. jgs
