Given numbers are 819, 438, 804, 549

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

Apply this formula for all numbers.

Step1:

LCM(819, 438) = 119574

GCD(819, 438) = ( 819 x 438 ) / 119574

= 819 / 438

= 819

Step2:

LCM(3, 804) = 804

GCD(3, 804) = ( 3 x 804 ) / 804

= 3 / 804

= 3

Step3:

LCM(3, 549) = 549

GCD(3, 549) = ( 3 x 549 ) / 549

= 3 / 549

= 3

So, Greatest Common Divisor of 819, 438, 804, 549 is 3
