The list of prime factors of all numbers are

Prime factors of 809 are 809

Prime factors of 665 are 5 x 7 x 19

Prime factors of 712 are 2 x 2 x 2 x 89

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

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

Given numbers are 809, 665, 712, 756

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

Apply this formula for all numbers.

Step1:

LCM(809, 665) = 537985

GCD(809, 665) = ( 809 x 665 ) / 537985

= 809 / 665

= 809

Step2:

LCM(1, 712) = 712

GCD(1, 712) = ( 1 x 712 ) / 712

= 1 / 712

= 1

Step3:

LCM(1, 756) = 756

GCD(1, 756) = ( 1 x 756 ) / 756

= 1 / 756

= 1

So, Greatest Common Divisor of 809, 665, 712, 756 is 1
