Given numbers are 669, 555, 789, 439

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

Apply this formula for all numbers.

Step1:

LCM(669, 555) = 123765

GCD(669, 555) = ( 669 x 555 ) / 123765

= 669 / 555

= 669

Step2:

LCM(3, 789) = 789

GCD(3, 789) = ( 3 x 789 ) / 789

= 3 / 789

= 3

Step3:

LCM(3, 439) = 1317

GCD(3, 439) = ( 3 x 439 ) / 1317

= 3 / 439

= 3

So, Greatest Common Divisor of 669, 555, 789, 439 is 1
