Given numbers are 489, 581, 702, 208

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 581 are 7 x 83

Prime factors of 702 are 2 x 3 x 3 x 3 x 13

Prime factors of 208 are 2 x 2 x 2 x 2 x 13

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

Given numbers are 489, 581, 702, 208

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

Apply this formula for all numbers.

Step1:

LCM(489, 581) = 284109

GCD(489, 581) = ( 489 x 581 ) / 284109

= 489 / 581

= 489

Step2:

LCM(1, 702) = 702

GCD(1, 702) = ( 1 x 702 ) / 702

= 1 / 702

= 1

Step3:

LCM(1, 208) = 208

GCD(1, 208) = ( 1 x 208 ) / 208

= 1 / 208

= 1

So, Greatest Common Divisor of 489, 581, 702, 208 is 1
