Given numbers are 255, 621, 656, 108

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 621 are 3 x 3 x 3 x 23

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

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

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

Given numbers are 255, 621, 656, 108

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

Apply this formula for all numbers.

Step1:

LCM(255, 621) = 52785

GCD(255, 621) = ( 255 x 621 ) / 52785

= 255 / 621

= 255

Step2:

LCM(3, 656) = 1968

GCD(3, 656) = ( 3 x 656 ) / 1968

= 3 / 656

= 3

Step3:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 255, 621, 656, 108 is 1
