Answer:3

Step-by-step explanation:

15: GCF= 5, 3

33: GCF= 11, 3

Greatest common factor (GCF) of 15 and 33 is 3. We will now calculate the prime factors of 15 and 33, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 15 and 33.
