Given numbers are 399, 664, 789, 923

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

Apply this formula for all numbers.

Step1:

LCM(399, 664) = 264936

GCD(399, 664) = ( 399 x 664 ) / 264936

= 399 / 664

= 399

Step2:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

Step3:

LCM(1, 923) = 923

GCD(1, 923) = ( 1 x 923 ) / 923

= 1 / 923

= 1

So, Greatest Common Divisor of 399, 664, 789, 923 is 1
