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

Apply this formula for all numbers.

Step1:

LCM(549, 828) = 50508

GCD(549, 828) = ( 549 x 828 ) / 50508

= 549 / 828

= 549

Step2:

LCM(9, 936) = 936

GCD(9, 936) = ( 9 x 936 ) / 936

= 9 / 936

= 9

Step3:

LCM(9, 645) = 1935

GCD(9, 645) = ( 9 x 645 ) / 1935

= 9 / 645

= 9

So, Greatest Common Divisor of 549, 828, 936, 645 is 3
