Given numbers are 321, 322, 420, 919

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 322 are 2 x 7 x 23

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 919 are 919

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

Given numbers are 321, 322, 420, 919

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

Apply this formula for all numbers.

Step1:

LCM(321, 322) = 103362

GCD(321, 322) = ( 321 x 322 ) / 103362

= 321 / 322

= 321

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

= 1 / 919

= 1

So, Greatest Common Divisor of 321, 322, 420, 919 is 1
