The list of prime factors of all numbers are

Prime factors of 686 are 2 x 7 x 7 x 7

Prime factors of 637 are 7 x 7 x 13

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 384 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 686, 637, 228, 384

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

Apply this formula for all numbers.

Step1:

LCM(686, 637) = 8918

GCD(686, 637) = ( 686 x 637 ) / 8918

= 686 / 637

= 686

Step2:

LCM(49, 228) = 11172

GCD(49, 228) = ( 49 x 228 ) / 11172

= 49 / 228

= 49

Step3:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

So, Greatest Common Divisor of 686, 637, 228, 384 is 1
