Given numbers are 549, 720, 57, 307

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

Apply this formula for all numbers.

Step1:

LCM(549, 720) = 43920

GCD(549, 720) = ( 549 x 720 ) / 43920

= 549 / 720

= 549

Step2:

LCM(9, 57) = 171

GCD(9, 57) = ( 9 x 57 ) / 171

= 9 / 57

= 9

Step3:

LCM(3, 307) = 921

GCD(3, 307) = ( 3 x 307 ) / 921

= 3 / 307

= 3

So, Greatest Common Divisor of 549, 720, 57, 307 is 1
