Brain Game: A Factor Fact


Factors are the integers that can be evenly divided into a given number. The factors of the number 4, for instance, are 1, 2, and 4, because each of those numbers can be divided into 4 without leaving a remainder. The factors for 5 are 1 and 5, since no other integers can be evenly divided into 5. The factors for 6 are 1, 2, 3, and 6. With that in mind, and ignoring negative numbers...

Here's the SOLUTION.


TWENTY-FOUR. The factors for 24 are 1, 2, 3, 4, 6, 8, 12 and 24.
