Yes it is because all of the integers of 324 add up to a number divisible by 3 (3+2+4=9). 324/3 = 108

The factors of 21 that add up to 8 are 1 and 7.
None. Factors don't add, they multiply.
No simply add the digits of the numerator 3 + 2 + 0 = 5 the digits must add to 9 if 9 will divide evenly. Take 324 the digits add up to nine and nine divides into 324 exactly 36 times!
Factors multiply. The same set of numbers won't add up to both 140 and 240, but 120 and 20 are factors of 240 that total 140.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.
