Given numbers are 311, 506, 455, 421

The list of prime factors of all numbers are

Prime factors of 311 are 311

Prime factors of 506 are 2 x 11 x 23

Prime factors of 455 are 5 x 7 x 13

Prime factors of 421 are 421

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

Given numbers are 311, 506, 455, 421

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

Apply this formula for all numbers.

Step1:

LCM(311, 506) = 157366

GCD(311, 506) = ( 311 x 506 ) / 157366

= 311 / 506

= 311

Step2:

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

= 1 / 455

= 1

Step3:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

So, Greatest Common Divisor of 311, 506, 455, 421 is 1
