Given numbers are 231, 666, 638, 903

The list of prime factors of all numbers are

Prime factors of 231 are 3 x 7 x 11

Prime factors of 666 are 2 x 3 x 3 x 37

Prime factors of 638 are 2 x 11 x 29

Prime factors of 903 are 3 x 7 x 43

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

Given numbers are 231, 666, 638, 903

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

Apply this formula for all numbers.

Step1:

LCM(231, 666) = 51282

GCD(231, 666) = ( 231 x 666 ) / 51282

= 231 / 666

= 231

Step2:

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

= 3 / 638

= 3

Step3:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 231, 666, 638, 903 is 1
