A factor is a number that can be multiplied by another whole number to equal your original number.
For example: The factors of 10 are - 1, 2, 5, 10 (10 has 4 unique factors)
To find a number with 13 factors, it must be fairly large.
We know the number you're looking for will have at least 2 factors, 1 and itself.
So we only need to find 11 more.
In fact, we can choose factors and make the number ourselves!
Remember, factors must be unique. They cannot repeat. A handy way to do this is to use prime numbers.
1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, and our number. (13 factors)
To find your number, multiply ALL of the prime numbers together. (Not 1, and not our number)
2*3*5*7*11*13*17*19*23*29*31 = ???
You'll find that the number you're looking for is
200,560,490,130
In fact, this number is the smallest composite number with the first 11 primes as factors!

Would you rather find all the factors of a number or find all the prime factors of a number?
Once all the prime factors of a number have been found, the number of factors the number has and what they are can be found. I'd be finding the prime factors first before finding all the factors of a number, so I'd rather find all the prime factors as it means I can stop before I have to do more work in finding all the factors.
