The list of prime factors of all numbers are

Prime factors of 383 are 383

Prime factors of 428 are 2 x 2 x 107

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 485 are 5 x 97

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

Given numbers are 383, 428, 644, 485

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

Apply this formula for all numbers.

Step1:

LCM(383, 428) = 163924

GCD(383, 428) = ( 383 x 428 ) / 163924

= 383 / 428

= 383

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 383, 428, 644, 485 is 1
