Given numbers are 638, 501, 420, 173

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 501 are 3 x 167

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 173 are 173

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

Given numbers are 638, 501, 420, 173

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

Apply this formula for all numbers.

Step1:

LCM(638, 501) = 319638

GCD(638, 501) = ( 638 x 501 ) / 319638

= 638 / 501

= 638

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 173) = 173

GCD(1, 173) = ( 1 x 173 ) / 173

= 1 / 173

= 1

So, Greatest Common Divisor of 638, 501, 420, 173 is 1
