Given numbers are 549, 897, 649, 810

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

Apply this formula for all numbers.

Step1:

LCM(549, 897) = 164151

GCD(549, 897) = ( 549 x 897 ) / 164151

= 549 / 897

= 549

Step2:

LCM(3, 649) = 1947

GCD(3, 649) = ( 3 x 649 ) / 1947

= 3 / 649

= 3

Step3:

LCM(1, 810) = 810

GCD(1, 810) = ( 1 x 810 ) / 810

= 1 / 810

= 1

So, Greatest Common Divisor of 549, 897, 649, 810 is 1
