Answer:
-  4 is the lowest possible integer that is a multiple of 4 but is also a factor of 12
 
Explanation:
Let's start out by listing out the factors and multiples of 12 and 4 respectively.
- => Factors of 12: 1, 2, 3, 4, 6, 12
 - => Multiples of 4: 4, 8, 12, 16, 20, 24....
 
We can clearly see that the lowest possible integer that is a multiple of 4 but is also a factor of 12 is 4. 
Hence, 4 is the answer.
