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

Apply this formula for all numbers.

Step1:

LCM(819, 711) = 64701

GCD(819, 711) = ( 819 x 711 ) / 64701

= 819 / 711

= 819

Step2:

LCM(9, 123) = 369

GCD(9, 123) = ( 9 x 123 ) / 369

= 9 / 123

= 9

Step3:

LCM(3, 369) = 369

GCD(3, 369) = ( 3 x 369 ) / 369

= 3 / 369

= 3

So, Greatest Common Divisor of 819, 711, 123, 369 is 3
