Question 529699
<font face="Times New Roman" size="+2">


If the number is a factor of 50, then it is less than 50.  There are only two numbers less than 50 where the sum of the digits is 1, one of them is 1 itself.  But that is not an even number.  Every other single digit number has a sum of digits equal to itself which is greater than 1.  Therefore the number you are looking for must be a two-digit number.  In order for the digits of a two digit number to add up to 1, what do you think the digits have to be?


HUGE HINT: Zero is a digit.
