What is the least common multiple of 12, 18 and 30?

 

the prime factors of 12 are          2,2 and 3

The prime factors of 18 are          2,3,and 3

The prime factors are 30 are        2,3,and 5

 

I need to include all the factor for each.

so I need    2,2,3   then     3   then 5

2*2*3*3*5 = 180
