Finding the Least Common Multiple of Two Numbers by Factoring
You can find the least common multiple (LCM) of two numbers by multiplying together the highest power of each factor found in either number.
A faster way to compute the LCM of two numbers and is , which can take advantage of the efficiency of the Euclidean algorithm.
