Given numbers are 568, 649, 720, 395

The list of prime factors of all numbers are

Prime factors of 568 are 2 x 2 x 2 x 71

Prime factors of 649 are 11 x 59

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

Prime factors of 395 are 5 x 79

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

Given numbers are 568, 649, 720, 395

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

Apply this formula for all numbers.

Step1:

LCM(568, 649) = 368632

GCD(568, 649) = ( 568 x 649 ) / 368632

= 568 / 649

= 568

Step2:

LCM(1, 720) = 720

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

= 1 / 720

= 1

Step3:

LCM(1, 395) = 395

GCD(1, 395) = ( 1 x 395 ) / 395

= 1 / 395

= 1

So, Greatest Common Divisor of 568, 649, 720, 395 is 1
