Given numbers are 388, 431, 378, 558

The list of prime factors of all numbers are

Prime factors of 388 are 2 x 2 x 97

Prime factors of 431 are 431

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

Prime factors of 558 are 2 x 3 x 3 x 31

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

Given numbers are 388, 431, 378, 558

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

Apply this formula for all numbers.

Step1:

LCM(388, 431) = 167228

GCD(388, 431) = ( 388 x 431 ) / 167228

= 388 / 431

= 388

Step2:

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

= 1 / 378

= 1

Step3:

LCM(1, 558) = 558

GCD(1, 558) = ( 1 x 558 ) / 558

= 1 / 558

= 1

So, Greatest Common Divisor of 388, 431, 378, 558 is 1
