Given numbers are 198, 780, 539, 321

The list of prime factors of all numbers are

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

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 539 are 7 x 7 x 11

Prime factors of 321 are 3 x 107

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

Given numbers are 198, 780, 539, 321

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

Apply this formula for all numbers.

Step1:

LCM(198, 780) = 25740

GCD(198, 780) = ( 198 x 780 ) / 25740

= 198 / 780

= 198

Step2:

LCM(6, 539) = 3234

GCD(6, 539) = ( 6 x 539 ) / 3234

= 6 / 539

= 6

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 198, 780, 539, 321 is 1
