The list of prime factors of all numbers are

Prime factors of 556 are 2 x 2 x 139

Prime factors of 663 are 3 x 13 x 17

Prime factors of 221 are 13 x 17

Prime factors of 537 are 3 x 179

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

Given numbers are 556, 663, 221, 537

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

Apply this formula for all numbers.

Step1:

LCM(556, 663) = 368628

GCD(556, 663) = ( 556 x 663 ) / 368628

= 556 / 663

= 556

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 537) = 537

GCD(1, 537) = ( 1 x 537 ) / 537

= 1 / 537

= 1

So, Greatest Common Divisor of 556, 663, 221, 537 is 1
