Given numbers are 690, 219, 594, 809

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

Apply this formula for all numbers.

Step1:

LCM(690, 219) = 50370

GCD(690, 219) = ( 690 x 219 ) / 50370

= 690 / 219

= 690

Step2:

LCM(3, 594) = 594

GCD(3, 594) = ( 3 x 594 ) / 594

= 3 / 594

= 3

Step3:

LCM(3, 809) = 2427

GCD(3, 809) = ( 3 x 809 ) / 2427

= 3 / 809

= 3

So, Greatest Common Divisor of 690, 219, 594, 809 is 1
