The list of prime factors of all numbers are

Prime factors of 645 are 3 x 5 x 43

Prime factors of 427 are 7 x 61

Prime factors of 570 are 2 x 3 x 5 x 19

Prime factors of 882 are 2 x 3 x 3 x 7 x 7

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

Given numbers are 645, 427, 570, 882

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

Apply this formula for all numbers.

Step1:

LCM(645, 427) = 275415

GCD(645, 427) = ( 645 x 427 ) / 275415

= 645 / 427

= 645

Step2:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

Step3:

LCM(1, 882) = 882

GCD(1, 882) = ( 1 x 882 ) / 882

= 1 / 882

= 1

So, Greatest Common Divisor of 645, 427, 570, 882 is 1
