The list of prime factors of all numbers are

Prime factors of 863 are 863

Prime factors of 174 are 2 x 3 x 29

Prime factors of 642 are 2 x 3 x 107

Prime factors of 388 are 2 x 2 x 97

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

Given numbers are 863, 174, 642, 388

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

Apply this formula for all numbers.

Step1:

LCM(863, 174) = 150162

GCD(863, 174) = ( 863 x 174 ) / 150162

= 863 / 174

= 863

Step2:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

Step3:

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

= 1 / 388

= 1

So, Greatest Common Divisor of 863, 174, 642, 388 is 1
