Given numbers are 385, 390, 198, 166

The list of prime factors of all numbers are

Prime factors of 385 are 5 x 7 x 11

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 166 are 2 x 83

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 385, 390, 198, 166

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(385, 390) = 30030

GCD(385, 390) = ( 385 x 390 ) / 30030

= 385 / 390

= 385

Step2:

LCM(5, 198) = 990

GCD(5, 198) = ( 5 x 198 ) / 990

= 5 / 198

= 5

Step3:

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

= 1 / 166

= 1

So, Greatest Common Divisor of 385, 390, 198, 166 is 1
