The GCF of 132 and 198 is 66. The factors of 132 are 2x66=2x2x3x11, The factors of 198 are 198= 3x66=2x11x3x3 The GCF is 66.

132 = 2 * 2 * 3 * 11 = 22 * 3 * 11198 = 2 * 3 * 3 * 11 = 2 * 32 * 11

NO ! Two numbers are relatively prime if they do not share any common factors. 198 and 216 are both even so without any further investigation they both have 2 as a factor and are thus NOT relatively prime. If you look further, they both have 32 as another factor.

2 x 2 x 3 x 11 = 132 2 x 3 x 3 x 11 = 198
