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

Apply this formula for all numbers.

Step1:

LCM(447, 789) = 117561

GCD(447, 789) = ( 447 x 789 ) / 117561

= 447 / 789

= 447

Step2:

LCM(3, 621) = 621

GCD(3, 621) = ( 3 x 621 ) / 621

= 3 / 621

= 3

Step3:

LCM(3, 267) = 267

GCD(3, 267) = ( 3 x 267 ) / 267

= 3 / 267

= 3

So, Greatest Common Divisor of 447, 789, 621, 267 is 3
