Given numbers are 321, 622, 722, 665

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 622 are 2 x 311

Prime factors of 722 are 2 x 19 x 19

Prime factors of 665 are 5 x 7 x 19

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

Given numbers are 321, 622, 722, 665

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

Apply this formula for all numbers.

Step1:

LCM(321, 622) = 199662

GCD(321, 622) = ( 321 x 622 ) / 199662

= 321 / 622

= 321

Step2:

LCM(1, 722) = 722

GCD(1, 722) = ( 1 x 722 ) / 722

= 1 / 722

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 321, 622, 722, 665 is 1
