The number 1111115
It means it is odd (ends in 1, 3, 5, 7, or 9), when you multiple the digits together you get 24 for an answer, and when you subtract the digits from each other you get 5. Hope this helps.
There is no solution to this problem. If each digit can be used once only then we have 5 odd numbered digits (1,3,5,7,9) and 4 even numbered digits (2,4,6,8). To create the two numbers that are added together requires the following combinations of digits. 5 Odd & 1 Even ....when added these will generate 2 Even digits & 1 Odd digit but the remaining digits are 3 Even. 4 Odd & 2 Even. These will generate 3 Even digits OR 1 Even digit & 2 Odd digits but the remaining digits are 1 Odd & 2 Even. 3 Odd & 3 Even. These generate 3 Odd digits OR 2 Even & 1 Odd digits but the remaining digits are 2 Odd & 1 Even. 2 Odd & 4 Even. These generate 3 Even digits OR 2 Odd & 1 Even digits but the remaining digits are 3 Odd & no Even.

It's an odd number so it obviously can't be divided by 2. The sum of its digits (1+6+5) is a multiple of 3, so the number itself is a multiple of 3. So it's not prime.
