Yes, a factor is a number that can be divided exactly into another number with no remainder.
To find the GCF of 13 and 39, you can list the factors of each number. The factors of 13 are 1, 13. The factors of 39 are 1, 3, 13, 39. 13 is the GCF of 13 and 39. 3 is a prime number has only two factors: 1 and 13. 13 will divide into 39 three times. Since 13 is a prime number that will divide into 39, it has to be the GCF of 13 and 39.
13 is a prime number so the only factors are 1 and itself.
The factors of 325 are 1, 5, 13, 25, 65, and 325. 5 and 13 are prime.
Multiples of 13 have 13 as a factor. 13, 26, 39 and so on.
4096 is the smallest number with exactly 13 factors. (Including 1 and itself as factors).192 is the smallest number with exactly 13 properfactors, (excluding the number itself).120 is the smallest number with at least 13 factors (it has 16 factors)To find the smallest number with exactly N factors (for example, N=12):Factor N into primes, (for example, 12= 2*2*3Subtract 1 from each of the prime factors (for example, 1,1,2)Sort them by largest first (for example, 2,1,1)Raise successive prime numbers to these powers (for example, 2^2,3^1,5^1)Multiply these together (for example: 4*3*5 = 60; 60 is the smallest number with exactly 12 factors).
4096
4096 is the smallest one. Since the number of factors depends on the exponents of the prime factors, plus one, multiplied together, the set of numbers that meets the requirements are of the form: p12, where p is a prime number.

Try 26 whose factors are: 1, 2, 13 and 26
