Given numbers are 305, 102, 272, 813

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 102 are 2 x 3 x 17

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 813 are 3 x 271

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

Given numbers are 305, 102, 272, 813

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

Apply this formula for all numbers.

Step1:

LCM(305, 102) = 31110

GCD(305, 102) = ( 305 x 102 ) / 31110

= 305 / 102

= 305

Step2:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 305, 102, 272, 813 is 1
