If those are the denominators, then the the negative part of -15 should be transferred to the numerator, eg if the fraction is 4/(-15) then make it (-4)/15, or if it is (-4)/(-15) make it (--4)/15 = 4/15.

Then the lcm of 15 and 10 is 30.

(Otherwise you are likely to have trouble in getting your signs right if you use a negative denominator.)
