Given numbers are 845, 638, 930, 628

The list of prime factors of all numbers are

Prime factors of 845 are 5 x 13 x 13

Prime factors of 638 are 2 x 11 x 29

Prime factors of 930 are 2 x 3 x 5 x 31

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 845, 638, 930, 628

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

Apply this formula for all numbers.

Step1:

LCM(845, 638) = 539110

GCD(845, 638) = ( 845 x 638 ) / 539110

= 845 / 638

= 845

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 628) = 628

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

= 1 / 628

= 1

So, Greatest Common Divisor of 845, 638, 930, 628 is 1
