Wait but what if you have 1 7 and 1 3 9

OpenStudy (mertsj):

You want the LCM of 1, 7, 1, 3, and 9 or the LCM of 17 and 139?

OpenStudy (anonymous):

No, I have 7, 9 and i need to get the LCM

OpenStudy (mertsj):

Write the prime factors of each number in exponential form. Then select the largest power of every DIFFERENT factor. That will be your LCM
