Given numbers are 310, 109, 720, 489

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 109 are 109

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

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 310, 109, 720, 489

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

Apply this formula for all numbers.

Step1:

LCM(310, 109) = 33790

GCD(310, 109) = ( 310 x 109 ) / 33790

= 310 / 109

= 310

Step2:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

Step3:

LCM(1, 489) = 489

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

= 1 / 489

= 1

So, Greatest Common Divisor of 310, 109, 720, 489 is 1
