If you denote N as the smallest of them, you get N + (N + 1) + (N + 2) = 72. That gives you:
3N + 3 = 72 OR 3N = 69.
Divide both sides by 3 and you get N = 23
divide 216 by 3 (72) subtract 1 and add 1 71, 72 and 73
The smallest of the three is 13.
The smallest of the three numbers is 22.
91 are.

The smallest is 15.
The smallest is 14.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
91 are.
