# How do you find the least common multiple of 9z to the fourth power if you don't know what z is?

## Answer

###### Wiki User

###### 09/19/2008

You don't, because you don't know if Z is a whole number and
because there is no LCM for less than two whole numbers. LCM is the
multiple of the highest power of prime factors in two or more
numbers. Example: LCM of 9, 15, and 25 is **225**, which is the
multiple of the highest power of prime factors in 9, 15, and 25 (32
x 52).
