Given numbers are 549, 221, 818, 439

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

Apply this formula for all numbers.

Step1:

LCM(549, 221) = 121329

GCD(549, 221) = ( 549 x 221 ) / 121329

= 549 / 221

= 549

Step2:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 549, 221, 818, 439 is 1
