Given numbers are 418, 406, 322, 621

The list of prime factors of all numbers are

Prime factors of 418 are 2 x 11 x 19

Prime factors of 406 are 2 x 7 x 29

Prime factors of 322 are 2 x 7 x 23

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

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

Given numbers are 418, 406, 322, 621

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

Apply this formula for all numbers.

Step1:

LCM(418, 406) = 84854

GCD(418, 406) = ( 418 x 406 ) / 84854

= 418 / 406

= 418

Step2:

LCM(2, 322) = 322

GCD(2, 322) = ( 2 x 322 ) / 322

= 2 / 322

= 2

Step3:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

So, Greatest Common Divisor of 418, 406, 322, 621 is 1
