Without the rest of the information, it will be one of these: 13, 26, 39, 52, 65, 78, 91
I'm betting on 65.

You need to add up the number of digits to the right of the decimal to find the number of digits in the answer. If the first factor has 2 digits to the right of the decimal point and the second factor has 3, the final answer will have 5 digits to the right of the decimal point.
The largest digits number with only 2 digits alike is 99
I did it by trial and error. 7^2 is 49. 4 + 9 = 13
65

16
67
The number you are looking for is 13. The other factor is 2, but 2 is even, so 13 is the only possibility. 52=13*2*2
1
656+5=1165/13=5
If the number with the digits reversed can have a leading 0 so that it is a 1-digit number, then 16. Otherwise 13.
5 is a factor of any whole number ending in 5; it is also a factor of any whole number of 2 or more digits ending in zero.
12
There is only one possible combination of a 13 digit number created from 13 digits. In a combination, the order of the digits does not matter so that 123 is the same as 132 or 312 etc. If there are 13 different digits (characters) there is 1 combination of 13 digits 13 combinations of 1 or of 12 digits 78 combinations of 2 or of 11 digits and so on There are 213 - 1 = 8191 in all. If the characters are not all different it is necessary to have more information.
