Given numbers are 615, 204, 339, 409

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

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

Prime factors of 339 are 3 x 113

Prime factors of 409 are 409

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

Given numbers are 615, 204, 339, 409

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

Apply this formula for all numbers.

Step1:

LCM(615, 204) = 41820

GCD(615, 204) = ( 615 x 204 ) / 41820

= 615 / 204

= 615

Step2:

LCM(3, 339) = 339

GCD(3, 339) = ( 3 x 339 ) / 339

= 3 / 339

= 3

Step3:

LCM(3, 409) = 1227

GCD(3, 409) = ( 3 x 409 ) / 1227

= 3 / 409

= 3

So, Greatest Common Divisor of 615, 204, 339, 409 is 1
