Given numbers are 639, 802, 422, 904

The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 802 are 2 x 401

Prime factors of 422 are 2 x 211

Prime factors of 904 are 2 x 2 x 2 x 113

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

Given numbers are 639, 802, 422, 904

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

Apply this formula for all numbers.

Step1:

LCM(639, 802) = 512478

GCD(639, 802) = ( 639 x 802 ) / 512478

= 639 / 802

= 639

Step2:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 639, 802, 422, 904 is 1
