Given numbers are 422, 721, 545, 621

The list of prime factors of all numbers are

Prime factors of 422 are 2 x 211

Prime factors of 721 are 7 x 103

Prime factors of 545 are 5 x 109

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 422, 721, 545, 621

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

Apply this formula for all numbers.

Step1:

LCM(422, 721) = 304262

GCD(422, 721) = ( 422 x 721 ) / 304262

= 422 / 721

= 422

Step2:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

Step3:

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

= 1 / 621

= 1

So, Greatest Common Divisor of 422, 721, 545, 621 is 1
