Given numbers are 809, 428, 567, 664

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

Apply this formula for all numbers.

Step1:

LCM(809, 428) = 346252

GCD(809, 428) = ( 809 x 428 ) / 346252

= 809 / 428

= 809

Step2:

LCM(1, 567) = 567

GCD(1, 567) = ( 1 x 567 ) / 567

= 1 / 567

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 809, 428, 567, 664 is 1
