The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 422 are 2 x 211

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 813, 270, 422, 309

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

Apply this formula for all numbers.

Step1:

LCM(813, 270) = 73170

GCD(813, 270) = ( 813 x 270 ) / 73170

= 813 / 270

= 813

Step2:

LCM(3, 422) = 1266

GCD(3, 422) = ( 3 x 422 ) / 1266

= 3 / 422

= 3

Step3:

LCM(1, 309) = 309

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

= 1 / 309

= 1

So, Greatest Common Divisor of 813, 270, 422, 309 is 1
