The list of prime factors of all numbers are

Prime factors of 553 are 7 x 79

Prime factors of 611 are 13 x 47

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 687 are 3 x 229

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

Given numbers are 553, 611, 656, 687

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

Apply this formula for all numbers.

Step1:

LCM(553, 611) = 337883

GCD(553, 611) = ( 553 x 611 ) / 337883

= 553 / 611

= 553

Step2:

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

= 1 / 656

= 1

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 553, 611, 656, 687 is 1
