Answer

945

Work Step by Step

The prime factored form of 15 is: $15=3\times5$ The prime factored form of 27 is: $27=3\times3\times3$ The prime factored form of 35 is: $35=5\times7$ Since the least common multiple (LCM) contains each different prime factor as many times as the most times it appears in any one of the factorizations, we obtain: LCM$=3\times3\times3\times5\times7=945$
