A certain number is a four digit number divisible by 2 and 3, the number on the thousand digit is odd and composite, the number on the hundred digit is neither prime nor composite, and the number on the ten digit is the smallest composite, so the four digit number is a number______ ．

The number on the thousand is odd and composite. The number on the thousand is 9. The number on the hundred is neither prime nor composite. The number on the hundred is 1. The number on the ten is the smallest composite. The number on the ten is 4. The sum of the numbers on each digit of the four digit is 9 + 1 + 4 = 14

A three digit number is neither a prime nor a composite number on the hundreds, the largest odd number on the tens, and the multiple of 2 and 3 on the individual bits. What is the number?

196

A three digit number is neither a prime nor a composite number on the hundreds, but the largest odd number on the tens, and the number is a multiple of 2 and 3. The three digit number is Or ．

1 is neither a prime nor a composite number, that is, the number on the hundreds is 1, the largest odd number is 9, that is, the number on the tens is 9, because it is a multiple of both 2 and 3, the number on each digit must be even, and the sum of the numbers on each digit is a multiple of 3, so the three digit is 192 or 198
