We can express this question as follows:


n+(n+2)+(n+4)=6

Now, we can sum the like terms (n's) and the integers in the previous expression. Then, we have:


(n+n+n)+(2+4)=6=3n+6\Rightarrow3n+6=6

Then, to solve the equation for n, we need to subtract 6 to both sides of the equation, and then divide by 3 to both sides too:


3n+6-6=6-6\Rightarrow3n=0\Rightarrow n=(3)/(3)n=(0)/(3)\Rightarrow n=0_{}

Then, we have that the three consecutive even integers are:


0+2+4=6

Therefore, the least integer is 0.
