Given numbers are 549, 285, 565, 789

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

Apply this formula for all numbers.

Step1:

LCM(549, 285) = 52155

GCD(549, 285) = ( 549 x 285 ) / 52155

= 549 / 285

= 549

Step2:

LCM(3, 565) = 1695

GCD(3, 565) = ( 3 x 565 ) / 1695

= 3 / 565

= 3

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 549, 285, 565, 789 is 1
