3*5*2 = 30
Multiplying denominators together will always give you a common denominator, but not necessarily the least common denominator. In this case, however, the product is also the lowest common denominator, since the values multiplied are all primes.

As the denominators 3, 2 and 5 are all prime numbers, the lowest common denominator is their product:
3*2*5 = 30.

To get a common denominator, just multiply all of the denominators together. Here, 3 x 5 x 2 = 30.
This may or may not be the LEAST common denominator, but it is a common denominator.

common denominator = numerator 1 * numerator 2 * numerator 3
= 3 * 5 * 2 = 30

adding
20/30+18/30+15/30=53/30=1.7666
