Given numbers are 720, 689, 560, 794

The list of prime factors of all numbers are

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

Prime factors of 689 are 13 x 53

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 794 are 2 x 397

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

Given numbers are 720, 689, 560, 794

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

Apply this formula for all numbers.

Step1:

LCM(720, 689) = 496080

GCD(720, 689) = ( 720 x 689 ) / 496080

= 720 / 689

= 720

Step2:

LCM(1, 560) = 560

GCD(1, 560) = ( 1 x 560 ) / 560

= 1 / 560

= 1

Step3:

LCM(1, 794) = 794

GCD(1, 794) = ( 1 x 794 ) / 794

= 1 / 794

= 1

So, Greatest Common Divisor of 720, 689, 560, 794 is 1
