Given numbers are 489, 350, 508, 644

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 350 are 2 x 5 x 5 x 7

Prime factors of 508 are 2 x 2 x 127

Prime factors of 644 are 2 x 2 x 7 x 23

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

Given numbers are 489, 350, 508, 644

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

Apply this formula for all numbers.

Step1:

LCM(489, 350) = 171150

GCD(489, 350) = ( 489 x 350 ) / 171150

= 489 / 350

= 489

Step2:

LCM(1, 508) = 508

GCD(1, 508) = ( 1 x 508 ) / 508

= 1 / 508

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 489, 350, 508, 644 is 1
