Given numbers are 321, 306, 720, 581

The list of prime factors of all numbers are

Prime factors of 321 are 3 x 107

Prime factors of 306 are 2 x 3 x 3 x 17

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

Prime factors of 581 are 7 x 83

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

Given numbers are 321, 306, 720, 581

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

Apply this formula for all numbers.

Step1:

LCM(321, 306) = 32742

GCD(321, 306) = ( 321 x 306 ) / 32742

= 321 / 306

= 321

Step2:

LCM(3, 720) = 720

GCD(3, 720) = ( 3 x 720 ) / 720

= 3 / 720

= 3

Step3:

LCM(3, 581) = 1743

GCD(3, 581) = ( 3 x 581 ) / 1743

= 3 / 581

= 3

So, Greatest Common Divisor of 321, 306, 720, 581 is 1
