Given numbers are 321, 323, 445, 489

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 323 are 17 x 19

Prime factors of 445 are 5 x 89

Prime factors of 489 are 3 x 163

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

Given numbers are 321, 323, 445, 489

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

Apply this formula for all numbers.

Step1:

LCM(321, 323) = 103683

GCD(321, 323) = ( 321 x 323 ) / 103683

= 321 / 323

= 321

Step2:

LCM(1, 445) = 445

GCD(1, 445) = ( 1 x 445 ) / 445

= 1 / 445

= 1

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 321, 323, 445, 489 is 1
