Answer:
Shown below
Step-by-step explanation:
First allocate the power of three to every number
= 
not sure what you mean by positive exponents, the exponents already are positive. Maybe you mean positive exponents and integers?
For example, for LCM (12,30) we find:
Using the set of prime numbers from each set with the highest exponent value we take 22 * 31 * 51 = 60. Therefore LCM (12,30) = 60.
Well, in 3 there are 24/8s.
That can fit four 5/8's in it with 4/8s left over.
So your answer is 4
