There are more than four: 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119.
Oh, what a happy little question! The four smallest three-digit composite numbers are 100, 102, 104, and 105. Just like painting a beautiful landscape, sometimes it's the smallest details that bring everything together. Keep exploring numbers, my friend!
The four smallest three digit composite numbers are: 100, 102, 104, 105 with sum 411.
102 & 104
both are composite numbers
4, 6, 8, 9, 104, 6, 8, 9, 10
102 104 105 106 108
100, 102, 104, 105, 106, and 792 .
99, 100, 102, 104, 105, 106, 108, 110, 111, 112, 114 (including 99 and 114)
102, 104, 105, 106, 108, 110, 111, 112, 114, 115, 116, 117, 118, 119, 120
They seem to mean that 97 is a prime number whereas the rest of them are composite numbers.
100 102 104 105 106 108 110
104 is composite. So is every other even number greater than 2.
