Given numbers are 238, 638, 511, 611

The list of prime factors of all numbers are

Prime factors of 238 are 2 x 7 x 17

Prime factors of 638 are 2 x 11 x 29

Prime factors of 511 are 7 x 73

Prime factors of 611 are 13 x 47

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

Given numbers are 238, 638, 511, 611

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

Apply this formula for all numbers.

Step1:

LCM(238, 638) = 75922

GCD(238, 638) = ( 238 x 638 ) / 75922

= 238 / 638

= 238

Step2:

LCM(2, 511) = 1022

GCD(2, 511) = ( 2 x 511 ) / 1022

= 2 / 511

= 2

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 238, 638, 511, 611 is 1
