The prime factor of 13 is 13 (13 is prime obviously)
The prime factors of 45 are 3 x 3 x 5
Since they have *no* factors in common that means their greatest common factor (GCF) will be 1.
More detail:
Factors of 13 are 1 and 13
Factors of 45 are 1, 3, 5, 9, 15 and 45
The only common factor is 1 which is therefore the greatest common factor.
P.S. Como is wrong with the answer of 13... that is *not* a common factor of 45. If you want further proof, use the following "GCF calculator" and enter 13 and 45.

13 is a prime number. therefore it's only factors are 1 and 13
45's factors are 1, 45, 3, 15, 5, 9
compare the factors for 13 and 45 and choose the largest.
the largest GCF in this case is 1

gcf is 1
prime factors of 13 = 1 x 13

13 is the greatest number that will divide into 13 and 45
GCF = 13
