The list of prime factors of all numbers are

Prime factors of 447 are 3 x 149

Prime factors of 286 are 2 x 11 x 13

Prime factors of 581 are 7 x 83

Prime factors of 628 are 2 x 2 x 157

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

Given numbers are 447, 286, 581, 628

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

Apply this formula for all numbers.

Step1:

LCM(447, 286) = 127842

GCD(447, 286) = ( 447 x 286 ) / 127842

= 447 / 286

= 447

Step2:

LCM(1, 581) = 581

GCD(1, 581) = ( 1 x 581 ) / 581

= 1 / 581

= 1

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 447, 286, 581, 628 is 1
