Given numbers are 722, 620, 695, 809

The list of prime factors of all numbers are

Prime factors of 722 are 2 x 19 x 19

Prime factors of 620 are 2 x 2 x 5 x 31

Prime factors of 695 are 5 x 139

Prime factors of 809 are 809

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

Given numbers are 722, 620, 695, 809

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

Apply this formula for all numbers.

Step1:

LCM(722, 620) = 223820

GCD(722, 620) = ( 722 x 620 ) / 223820

= 722 / 620

= 722

Step2:

LCM(2, 695) = 1390

GCD(2, 695) = ( 2 x 695 ) / 1390

= 2 / 695

= 2

Step3:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

So, Greatest Common Divisor of 722, 620, 695, 809 is 1
