Given numbers are 390, 439, 766, 819

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

Apply this formula for all numbers.

Step1:

LCM(390, 439) = 171210

GCD(390, 439) = ( 390 x 439 ) / 171210

= 390 / 439

= 390

Step2:

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

= 1 / 766

= 1

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 390, 439, 766, 819 is 1
