Factors of 3

1, 3

3 is prime: only factor pair is (1, 3), confirmed by trial division up to √3 ≈ 1.7 turning up nothing else. 3's full pair list is (1, 3), for 2 divisors in total. 3's divisors other than 3 itself sum to just 1, 2 below 3: the common deficient case. 3 is odd, digit sum 3 for 3; none of 2-12 divide 3 evenly. 3 has 2 divisors; 2 has 2 and 4 has 3, so 4 wins here. 3 divided by its largest divisor, 1, gives 3.
