Given numbers are 855, 684, 222, 439

The list of prime factors of all numbers are

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 222 are 2 x 3 x 37

Prime factors of 439 are 439

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

Given numbers are 855, 684, 222, 439

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

Apply this formula for all numbers.

Step1:

LCM(855, 684) = 3420

GCD(855, 684) = ( 855 x 684 ) / 3420

= 855 / 684

= 855

Step2:

LCM(171, 222) = 12654

GCD(171, 222) = ( 171 x 222 ) / 12654

= 171 / 222

= 171

Step3:

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

= 3 / 439

= 3

So, Greatest Common Divisor of 855, 684, 222, 439 is 1
