Given numbers are 444, 621, 309, 306

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

Apply this formula for all numbers.

Step1:

LCM(444, 621) = 91908

GCD(444, 621) = ( 444 x 621 ) / 91908

= 444 / 621

= 444

Step2:

LCM(3, 309) = 309

GCD(3, 309) = ( 3 x 309 ) / 309

= 3 / 309

= 3

Step3:

LCM(3, 306) = 306

GCD(3, 306) = ( 3 x 306 ) / 306

= 3 / 306

= 3

So, Greatest Common Divisor of 444, 621, 309, 306 is 3
