Given numbers are 549, 231, 277, 720

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

Apply this formula for all numbers.

Step1:

LCM(549, 231) = 42273

GCD(549, 231) = ( 549 x 231 ) / 42273

= 549 / 231

= 549

Step2:

LCM(3, 277) = 831

GCD(3, 277) = ( 3 x 277 ) / 831

= 3 / 277

= 3

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 549, 231, 277, 720 is 1
