If factors include 1 and the number itself then the any number (n) with only 4 factors has to be the product of two prime numbers, p1 and p2. The factors are then n, p1, p2, and 1. The largest 3-digit number with only 4 factors is 998. The factors are 998, 499, 2 and 1

No. There's no two digit numbers that could do this. The largest two digit number is 99. If you add 99 to itself, you only get 198, which is much smaller than a four digit number.

the answer would seem to be ten.

10, which has the factors 1,2,5 and 10. If the trivial pair 1 and the number itself are disallowed, the answer is 12 with factors 2,3,4 and 6.
