Given numbers are 255, 905, 130, 556

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 905 are 5 x 181

Prime factors of 130 are 2 x 5 x 13

Prime factors of 556 are 2 x 2 x 139

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

Given numbers are 255, 905, 130, 556

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

Apply this formula for all numbers.

Step1:

LCM(255, 905) = 46155

GCD(255, 905) = ( 255 x 905 ) / 46155

= 255 / 905

= 255

Step2:

LCM(5, 130) = 130

GCD(5, 130) = ( 5 x 130 ) / 130

= 5 / 130

= 5

Step3:

LCM(5, 556) = 2780

GCD(5, 556) = ( 5 x 556 ) / 2780

= 5 / 556

= 5

So, Greatest Common Divisor of 255, 905, 130, 556 is 1
