The largest three-digit positive integer is 999. It is the highest number that can be represented with three digits, where each digit can range from 0 to 9, with the first digit being non-zero.
The smallest positive integer with four different digits is 1023. This number uses the smallest digits available (1, 0, 2, and 3) while ensuring that the first digit is not zero, thus maintaining its status as a positive integer.
It is -987. The smallest positive 3-digit integer with unique digits is 102.

The answer is a negative or positive integer with one or two digits.
The largest composite integer before 100 is 99 - its positive integer factors are 1, 3, 9, 11, 33, 99.
1
The set of positive integers is {1, 2, 3, 4, 5, ...}. Because the values approach positive infinity there is no largest positive integer. If you pick any positive integer, you can always create a larger one by simply adding 1 to it. So there can be no largest positive integer.
The smallest positive integer with four different digits is 1023. This number uses the smallest digits available (1, 0, 2, and 3) while ensuring that the first digit is not zero, thus maintaining its status as a positive integer.

It is -987. The smallest positive 3-digit integer with unique digits is 102.
The greatest 4 digit integer divisible by 3 (and therefore a multiple of 3) is 9999.

The largest factor of any positive integer is the number itself.
Let the three-digit integer be ( x ) and the two-digit integer be ( y ). According to the problem, ( x - y = 288 ), which implies ( x = y + 288 ). The digits used are 7, 8, 2, 3, and 0. After testing possible combinations, the solution is ( x = 782 ) and ( y = 494 ). Therefore, the sum of the three-digit integer ( x ) and the two-digit integer ( y ) is ( 782 + 494 = 1276 ).
The first 3 digit integer being a positive multiple of 30 is 120. The final 3 digit integer being a positive multiple of 30 is 990. 990 - 120 = 870. 870 ÷ 30 = 29 But, as 29 is the difference between the two limits and the limits themselves are included then there are 29 + 1 = 30 such numbers.
The answer is a negative or positive integer with one or two digits.
