The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 406 are 2 x 7 x 29

Prime factors of 921 are 3 x 307

Prime factors of 129 are 3 x 43

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

Given numbers are 618, 406, 921, 129

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

Apply this formula for all numbers.

Step1:

LCM(618, 406) = 125454

GCD(618, 406) = ( 618 x 406 ) / 125454

= 618 / 406

= 618

Step2:

LCM(2, 921) = 1842

GCD(2, 921) = ( 2 x 921 ) / 1842

= 2 / 921

= 2

Step3:

LCM(1, 129) = 129

GCD(1, 129) = ( 1 x 129 ) / 129

= 1 / 129

= 1

So, Greatest Common Divisor of 618, 406, 921, 129 is 1
