Given numbers are 391, 422, 472, 684

The list of prime factors of all numbers are

Prime factors of 391 are 17 x 23

Prime factors of 422 are 2 x 211

Prime factors of 472 are 2 x 2 x 2 x 59

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

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

Given numbers are 391, 422, 472, 684

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

Apply this formula for all numbers.

Step1:

LCM(391, 422) = 165002

GCD(391, 422) = ( 391 x 422 ) / 165002

= 391 / 422

= 391

Step2:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 391, 422, 472, 684 is 1
