Given numbers are 422, 389, 570, 620

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 389 are 389

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

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 422, 389, 570, 620

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

Apply this formula for all numbers.

Step1:

LCM(422, 389) = 164158

GCD(422, 389) = ( 422 x 389 ) / 164158

= 422 / 389

= 422

Step2:

LCM(1, 570) = 570

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

= 1 / 570

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 422, 389, 570, 620 is 1
