Let N-2,N,and N%2B2 be the integers.
N-2%2BN%2BN%2B2%3E=36
3N%3E=36
N%3E=12
The next odd integer would be 13.
So 11,13,and 15 are the least triple of odd numbers for which the sum is at least 36.

Let smallest integer be S
Then others are S + 2, and S + 4
We then have: S+%2B+S+%2B+2+%2B+S+%2B+4+%3E=+36
3S+%2B+6+%3E=+36
3S+%3E=+30
Smallest integer, or S+%3E=+30%2F3, or S+%3E=+10
