Given numbers are 128, 684, 547, 403

The list of prime factors of all numbers are

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Prime factors of 547 are 547

Prime factors of 403 are 13 x 31

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

Given numbers are 128, 684, 547, 403

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

Apply this formula for all numbers.

Step1:

LCM(128, 684) = 21888

GCD(128, 684) = ( 128 x 684 ) / 21888

= 128 / 684

= 128

Step2:

LCM(4, 547) = 2188

GCD(4, 547) = ( 4 x 547 ) / 2188

= 4 / 547

= 4

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 128, 684, 547, 403 is 1
