Given numbers are 638, 854, 685, 873

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 854 are 2 x 7 x 61

Prime factors of 685 are 5 x 137

Prime factors of 873 are 3 x 3 x 97

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

Given numbers are 638, 854, 685, 873

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

Apply this formula for all numbers.

Step1:

LCM(638, 854) = 272426

GCD(638, 854) = ( 638 x 854 ) / 272426

= 638 / 854

= 638

Step2:

LCM(2, 685) = 1370

GCD(2, 685) = ( 2 x 685 ) / 1370

= 2 / 685

= 2

Step3:

LCM(1, 873) = 873

GCD(1, 873) = ( 1 x 873 ) / 873

= 1 / 873

= 1

So, Greatest Common Divisor of 638, 854, 685, 873 is 1
