The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 985 are 5 x 197

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 386 are 2 x 193

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

Given numbers are 305, 985, 656, 386

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

Apply this formula for all numbers.

Step1:

LCM(305, 985) = 60085

GCD(305, 985) = ( 305 x 985 ) / 60085

= 305 / 985

= 305

Step2:

LCM(5, 656) = 3280

GCD(5, 656) = ( 5 x 656 ) / 3280

= 5 / 656

= 5

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 305, 985, 656, 386 is 1
