The list of prime factors of all numbers are

Prime factors of 989 are 23 x 43

Prime factors of 591 are 3 x 197

Prime factors of 682 are 2 x 11 x 31

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

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

Given numbers are 989, 591, 682, 720

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

Apply this formula for all numbers.

Step1:

LCM(989, 591) = 584499

GCD(989, 591) = ( 989 x 591 ) / 584499

= 989 / 591

= 989

Step2:

LCM(1, 682) = 682

GCD(1, 682) = ( 1 x 682 ) / 682

= 1 / 682

= 1

Step3:

LCM(1, 720) = 720

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

= 1 / 720

= 1

So, Greatest Common Divisor of 989, 591, 682, 720 is 1
