Work Step by Step

The prime factored form of 9 is: $9=3\times3$ The prime factored form of 12 is: $12=2\times2\times3$ 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$=2\times2\times3\times3=36$ Therefore, the question statement is false.
