    Hi All,

    I am trying to make a programming code to find the LCM between the following
    numbers.
    I DO NOT want to use Prime Factorization but wish to setup some kind of
    table multiplication process until required results are found.

    Here are the correct results shown using LCM function

    LCM[Rationalize[1.4137, 0],
    Rationalize[2.5, 0], 5,
    Rationalize[12.5, 0]]
    353425
    N[%/{Rationalize[1.4137, 0],
    Rationalize[2.5, 0], 5,
    Rationalize[12.5, 0]}]
    {250000., 141370., 70685., 28274.}

    Any help & advice gratefully received.
    Many thanks for your help & attention.

    Best Regards - Lea Rebanks...

    If you mean that you'd like to implement an LCM algorithm yourself,
    compute the GCD first with the Euclidean algorithm (look it up), and
    use the result to find the LCM.
