Given numbers are 489, 320, 475, 930

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 475 are 5 x 5 x 19

Prime factors of 930 are 2 x 3 x 5 x 31

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

Given numbers are 489, 320, 475, 930

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

Apply this formula for all numbers.

Step1:

LCM(489, 320) = 156480

GCD(489, 320) = ( 489 x 320 ) / 156480

= 489 / 320

= 489

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

Step3:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

So, Greatest Common Divisor of 489, 320, 475, 930 is 1
