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$=3\times3\times3\times5\times7=945$
