Answer:

[tex]LCM(1,2,12,30,84,165)=2^2*3*5*7*11*1=4620[/tex]

Step-by-step explanation:

To find the LCM of 1,2,12,30,84,165 you must first find the prime factors of 12,30,84 and 165

12| 2               30| 2             84| 2                   165| 3

6 | 2               15 | 3             42| 2                   55 | 5
