Given numbers are 819, 412, 485, 439

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

Apply this formula for all numbers.

Step1:

LCM(819, 412) = 337428

GCD(819, 412) = ( 819 x 412 ) / 337428

= 819 / 412

= 819

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 819, 412, 485, 439 is 1
