Yes

As there is debate as to whether 0 (zero) is a member of the set of natural numbers or not, by asking "is it possible", it must be permitted to allow the acceptance of the more liberal definition. 
In addition, as it can also be defined that 0 can be a perfect square (02 = 0), we can see that 0 x 1 x 2 = 02; and, since 0, 1, and 2 are three consecutive natural numbers, the answer is yes.
