Given numbers are 489, 280, 638, 322

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 280 are 2 x 2 x 2 x 5 x 7

Prime factors of 638 are 2 x 11 x 29

Prime factors of 322 are 2 x 7 x 23

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

Given numbers are 489, 280, 638, 322

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

Apply this formula for all numbers.

Step1:

LCM(489, 280) = 136920

GCD(489, 280) = ( 489 x 280 ) / 136920

= 489 / 280

= 489

Step2:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

Step3:

LCM(1, 322) = 322

GCD(1, 322) = ( 1 x 322 ) / 322

= 1 / 322

= 1

So, Greatest Common Divisor of 489, 280, 638, 322 is 1
