Given numbers are 684, 455, 855, 422

The list of prime factors of all numbers are

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

Prime factors of 455 are 5 x 7 x 13

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

Prime factors of 422 are 2 x 211

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

Given numbers are 684, 455, 855, 422

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

Apply this formula for all numbers.

Step1:

LCM(684, 455) = 311220

GCD(684, 455) = ( 684 x 455 ) / 311220

= 684 / 455

= 684

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

So, Greatest Common Divisor of 684, 455, 855, 422 is 1
