Given numbers are 204, 642, 520, 305

The list of prime factors of all numbers are

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 642 are 2 x 3 x 107

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 305 are 5 x 61

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

Given numbers are 204, 642, 520, 305

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

Apply this formula for all numbers.

Step1:

LCM(204, 642) = 21828

GCD(204, 642) = ( 204 x 642 ) / 21828

= 204 / 642

= 204

Step2:

LCM(6, 520) = 1560

GCD(6, 520) = ( 6 x 520 ) / 1560

= 6 / 520

= 6

Step3:

LCM(2, 305) = 610

GCD(2, 305) = ( 2 x 305 ) / 610

= 2 / 305

= 2

So, Greatest Common Divisor of 204, 642, 520, 305 is 1
