Given numbers are 556, 257, 276, 321

The list of prime factors of all numbers are

Prime factors of 556 are 2 x 2 x 139

Prime factors of 257 are 257

Prime factors of 276 are 2 x 2 x 3 x 23

Prime factors of 321 are 3 x 107

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

Given numbers are 556, 257, 276, 321

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

Apply this formula for all numbers.

Step1:

LCM(556, 257) = 142892

GCD(556, 257) = ( 556 x 257 ) / 142892

= 556 / 257

= 556

Step2:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

Step3:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

So, Greatest Common Divisor of 556, 257, 276, 321 is 1
