There are many such triplets.
Consider any number ending in 4. The next two numbers will end in 5 and 6. The first and last will be divisible by two and the middle one by 5.
To compile a complete list of all such triplets, first draw up a list of all odd numbers that are not prime eg 9, 15, 21 etc. A triplet with that number in the middle will meet your requirements.
There are no such numbers. The smallest set of three consecutive composite numbers is {8, 9, 10} and the product of these numbers is 720.
8, 9, 10
Basically, composite numbers are the non-prime numbers. Take a table of prime numbers, and look for any two prime numbers, one after the other, that have a difference greater than 2. Any numbers in between are consecutive composite numbers. For example, the next prime number after 13 is 17; that makes 14, 15, and 16 three consecutive non-primes, i.e., composite numbers.
24, 25 and 26 is one possible triplet.

The three composite numbers are 28, 30 and 32. Their sum is 90.

The four smallest three digit composite numbers are: 100, 102, 104, 105 with sum 411.
If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.If you take three consecutive odd (or three consecutive even) numbers, one of the three will always be a multiple of 3.
There are no three consecutive numbers with a sum of 170.
Three composite numbers are 1 3 6
There are no sets of three consecutive numbers totaling 118.
