Given numbers are 198, 660, 622, 213

The list of prime factors of all numbers are

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

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

Prime factors of 622 are 2 x 311

Prime factors of 213 are 3 x 71

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

Given numbers are 198, 660, 622, 213

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

Apply this formula for all numbers.

Step1:

LCM(198, 660) = 1980

GCD(198, 660) = ( 198 x 660 ) / 1980

= 198 / 660

= 198

Step2:

LCM(66, 622) = 20526

GCD(66, 622) = ( 66 x 622 ) / 20526

= 66 / 622

= 66

Step3:

LCM(2, 213) = 426

GCD(2, 213) = ( 2 x 213 ) / 426

= 2 / 213

= 2

So, Greatest Common Divisor of 198, 660, 622, 213 is 1
