The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 542 are 2 x 271

Prime factors of 550 are 2 x 5 x 5 x 11

Prime factors of 398 are 2 x 199

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

Given numbers are 321, 542, 550, 398

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

Apply this formula for all numbers.

Step1:

LCM(321, 542) = 173982

GCD(321, 542) = ( 321 x 542 ) / 173982

= 321 / 542

= 321

Step2:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

Step3:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

So, Greatest Common Divisor of 321, 542, 550, 398 is 1
