Given numbers are 204, 556, 609, 405

The list of prime factors of all numbers are

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

Prime factors of 556 are 2 x 2 x 139

Prime factors of 609 are 3 x 7 x 29

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

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

Given numbers are 204, 556, 609, 405

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

Apply this formula for all numbers.

Step1:

LCM(204, 556) = 28356

GCD(204, 556) = ( 204 x 556 ) / 28356

= 204 / 556

= 204

Step2:

LCM(4, 609) = 2436

GCD(4, 609) = ( 4 x 609 ) / 2436

= 4 / 609

= 4

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 204, 556, 609, 405 is 1
