Given numbers are 615, 421, 204, 309

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

Prime factors of 421 are 421

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

Prime factors of 309 are 3 x 103

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

Given numbers are 615, 421, 204, 309

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

Apply this formula for all numbers.

Step1:

LCM(615, 421) = 258915

GCD(615, 421) = ( 615 x 421 ) / 258915

= 615 / 421

= 615

Step2:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 615, 421, 204, 309 is 1
