Question 119217
I'll do the first 2 to help you get started.



#1





First, list the prime factorization of each number. If you need help with prime factorization, check out this <a href="http://www.algebra.com/algebra/homework/divisibility/factor-any-number.solver">solver</a>.



5: 5



3: 3



2: 2



Now highlight the unique factors. Remember, highlight the factors that occur most frequently



5: <font color="red">5</font>



3: <font color="red">3</font>



2: <font color="red">2</font>



Now multiply all of the highlighted factors


2*3*5=30


So the LCM of 5, 3, and 2 is 30

3: <font color="red">3</font>



4: <font color="red">2*2</font>



5: <font color="red">5</font>



Now multiply all of the highlighted factors


2*2*3*5=60


So the LCM of 3, 4, and 5 is 60
