Given numbers are 218, 351, 622, 421

The list of prime factors of all numbers are

Prime factors of 218 are 2 x 109

Prime factors of 351 are 3 x 3 x 3 x 13

Prime factors of 622 are 2 x 311

Prime factors of 421 are 421

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

Given numbers are 218, 351, 622, 421

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

Apply this formula for all numbers.

Step1:

LCM(218, 351) = 76518

GCD(218, 351) = ( 218 x 351 ) / 76518

= 218 / 351

= 218

Step2:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

Step3:

LCM(1, 421) = 421

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

= 1 / 421

= 1

So, Greatest Common Divisor of 218, 351, 622, 421 is 1
