Given numbers are 660, 130, 231, 198

The list of prime factors of all numbers are

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 130 are 2 x 5 x 13

Prime factors of 231 are 3 x 7 x 11

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

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

Given numbers are 660, 130, 231, 198

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

Apply this formula for all numbers.

Step1:

LCM(660, 130) = 8580

GCD(660, 130) = ( 660 x 130 ) / 8580

= 660 / 130

= 660

Step2:

LCM(10, 231) = 2310

GCD(10, 231) = ( 10 x 231 ) / 2310

= 10 / 231

= 10

Step3:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

So, Greatest Common Divisor of 660, 130, 231, 198 is 1
