Answer 1

Answer:

The GCF of 198 and 360 is 18.

Steps to find GCF

Find the prime factorization of 198

198 = 2 × 3 × 3 × 11

Find the prime factorization of 360

360 = 2 × 2 × 2 × 3 × 3 × 5

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3 × 3

GCF = 18

Answer 2

Step-by-step explanation:

198=3*3*2*11
