Given numbers are 638, 407, 710, 302

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 407 are 11 x 37

Prime factors of 710 are 2 x 5 x 71

Prime factors of 302 are 2 x 151

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

Given numbers are 638, 407, 710, 302

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

Apply this formula for all numbers.

Step1:

LCM(638, 407) = 23606

GCD(638, 407) = ( 638 x 407 ) / 23606

= 638 / 407

= 638

Step2:

LCM(11, 710) = 7810

GCD(11, 710) = ( 11 x 710 ) / 7810

= 11 / 710

= 11

Step3:

LCM(1, 302) = 302

GCD(1, 302) = ( 1 x 302 ) / 302

= 1 / 302

= 1

So, Greatest Common Divisor of 638, 407, 710, 302 is 1
