Sally is thinking of a number. The product of the digits is one half of the number. What is the smallest positive, two-digit integer she could be thinking of?

We know the number must NOT contain 0, and the number must be EVEN. That reduces the amount of numbers we have to guess.

 

The answer is 36

 

 

Check: 3*6 = 18, and 18 is half of 36
