Greatest Common Denominator (GCD) and Least Common Multiple (LCM) are two fundamental concepts that every student of algebra must learn. This app not only finds the answers, but explains them too. Enter up to four different numbers and see prime number factoring for each of them along with the GCD and LCM values, and explanations of each. Great for learning or checking homework answers.
