The list of prime factors of all numbers are

Prime factors of 287 are 7 x 41

Prime factors of 530 are 2 x 5 x 53

Prime factors of 618 are 2 x 3 x 103

Prime factors of 205 are 5 x 41

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

Given numbers are 287, 530, 618, 205

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

Apply this formula for all numbers.

Step1:

LCM(287, 530) = 152110

GCD(287, 530) = ( 287 x 530 ) / 152110

= 287 / 530

= 287

Step2:

LCM(1, 618) = 618

GCD(1, 618) = ( 1 x 618 ) / 618

= 1 / 618

= 1

Step3:

LCM(1, 205) = 205

GCD(1, 205) = ( 1 x 205 ) / 205

= 1 / 205

= 1

So, Greatest Common Divisor of 287, 530, 618, 205 is 1
