There is no such number. Just as numbers don't stop, the possible number of factors is infinite.
The largest one digit number that has three factors is 9. Its factors are 1, 3, and 9.
This is a nonsensical question. There are more than 13 multiples of 10 - in fact there are an infinite number. And there are multiples of 10 which have an infinite number of factors - so there cannot be a "largest" number of factors.
The maximum number of different factors is 12 and there are 5 numbers in 1-100 which have 12 factors.

It is 97 and its factors are itself and one
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

The prime factors of 100 are 2 and 5; the largest of these is 5. The largest prime number under 100 is 97.
