Given numbers are 620, 422, 588, 555

The list of prime factors of all numbers are

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

Prime factors of 422 are 2 x 211

Prime factors of 588 are 2 x 2 x 3 x 7 x 7

Prime factors of 555 are 3 x 5 x 37

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

Given numbers are 620, 422, 588, 555

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

Apply this formula for all numbers.

Step1:

LCM(620, 422) = 130820

GCD(620, 422) = ( 620 x 422 ) / 130820

= 620 / 422

= 620

Step2:

LCM(2, 588) = 588

GCD(2, 588) = ( 2 x 588 ) / 588

= 2 / 588

= 2

Step3:

LCM(2, 555) = 1110

GCD(2, 555) = ( 2 x 555 ) / 1110

= 2 / 555

= 2

So, Greatest Common Divisor of 620, 422, 588, 555 is 1
