656+5=1165/13=5
2, 3 and 13
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
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.
2 and 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.
It will be 13 because 13 is a prime number
The answer is 13.
