Hcf= 12

hope I will correct

Answer 2

most often as a factor and write it that many times in a new list.

The new superset list is 

2, 2, 2, 3, 3, 3, 5, 5, 7

Multiply these factors together to find the LCM.

LCM = 2 x 2 x 2 x 3 x 3 x 3 x 5 x 5 x 7 = 37800

In exponential form:

LCM = 23 x 33 x 52 x 71 = 37800

LCM = 37800

Therefore,

LCM(72, 108, 2100) = 37,800
