Provided that the first digit cannot be 0, 1000 is the smallest number with four digits. Otherwise there are smaller numbers with 0 to thousandth digit such as 0100, 0050. The smallest integer in such instance is 0000.
That would be the same as the smallest four-digit even number: 1,000, which also happens to be the smallest four-digit whole number.
To find a four-digit number divisible by both 23 and 9, we first determine the least common multiple (LCM) of the two numbers. The LCM of 23 and 9 is 207. The smallest four-digit number is 1000, and the largest is 9999. Dividing 1000 by 207 gives approximately 4.83, so the smallest four-digit number that is a multiple of 207 is 5 × 207 = 1035.
If you allow non integers, then your smallest four-digit number would be .0001. If you only allow integers, then your smallest four-digit number would be 1000. Your largest four-digit number would be 9999.
The smallest four digit number is 1000. It is even so 1001 is the smallest four digit number that is odd.

This depends on what you mean by smallest. The smallest four-digit whole number is 1,000; the smallest four-digit real number is .0001 (1/10,000); the smallest four-digit integer is -9,999.
The smallest four digit odd integer is 1001.
Provided that the first digit cannot be 0, 1000 is the smallest number with four digits. Otherwise there are smaller numbers with 0 to thousandth digit such as 0100, 0050. The smallest integer in such instance is 0000.
That would be the same as the smallest four-digit even number: 1,000, which also happens to be the smallest four-digit whole number.
If you allow non integers, then your smallest four-digit number would be .0001. If you only allow integers, then your smallest four-digit number would be 1000. Your largest four-digit number would be 9999.
The smallest four digit number is 1000. It is even so 1001 is the smallest four digit number that is odd.
The smallest four-digit number in which no digit is repeated is 1023. It starts with the smallest digit (1) to ensure it's a four-digit number, followed by the next smallest digits (0, 2, and 3) without any repetitions.
The smallest four-digit number not using zero is 1000. In a four-digit number, the first digit cannot be zero, so the smallest possible value for the first digit is 1. The remaining three digits can be any number from 0-9, so the smallest possible four-digit number is 1000.
The smallest four digit whole number is 1000.
The smallest four digit whole number is 1000.
