    What is the lowest common demoninator of 1/3, 1/5, 1/20, and 1/50?

    all of these have the same denominator, 1.

    Are you sure you don't mean Least Common Multiple?

    jallen26: Do you mean Least Common Multiple (LCM)?

    I asked the wrong question... I meant 1/3, 1/5, 1/20, and 1/50.

    Find the least common multiple of the denominators
    Start with one pair and then add the next one in
    1/(LCM(3,LCM(5,LCM(20,50))))
