Given numbers are 284, 378, 684, 557

The list of prime factors of all numbers are

Prime factors of 284 are 2 x 2 x 71

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Prime factors of 557 are 557

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

Given numbers are 284, 378, 684, 557

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

Apply this formula for all numbers.

Step1:

LCM(284, 378) = 53676

GCD(284, 378) = ( 284 x 378 ) / 53676

= 284 / 378

= 284

Step2:

LCM(2, 684) = 684

GCD(2, 684) = ( 2 x 684 ) / 684

= 2 / 684

= 2

Step3:

LCM(2, 557) = 1114

GCD(2, 557) = ( 2 x 557 ) / 1114

= 2 / 557

= 2

So, Greatest Common Divisor of 284, 378, 684, 557 is 1
