Given numbers are 638, 930, 938, 493

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 930 are 2 x 3 x 5 x 31

Prime factors of 938 are 2 x 7 x 67

Prime factors of 493 are 17 x 29

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

Given numbers are 638, 930, 938, 493

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

Apply this formula for all numbers.

Step1:

LCM(638, 930) = 296670

GCD(638, 930) = ( 638 x 930 ) / 296670

= 638 / 930

= 638

Step2:

LCM(2, 938) = 938

GCD(2, 938) = ( 2 x 938 ) / 938

= 2 / 938

= 2

Step3:

LCM(2, 493) = 986

GCD(2, 493) = ( 2 x 493 ) / 986

= 2 / 493

= 2

So, Greatest Common Divisor of 638, 930, 938, 493 is 1
