first get the prime factors 15 = 3*5 18 = 2*3*3 25 = 5*5 The LCM will be the product of these numbers except that where a number occurs more that once in different factors it is only used once. For example a 5 in factors of 15 matches one in factors of 25 so only one of these are used to get the LCM.

so there are only 2 5's in the answer - that is 5^2 can you find the rest of the LCM?
