Given numbers are 819, 676, 30, 447

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

Apply this formula for all numbers.

Step1:

LCM(819, 676) = 42588

GCD(819, 676) = ( 819 x 676 ) / 42588

= 819 / 676

= 819

Step2:

LCM(13, 30) = 390

GCD(13, 30) = ( 13 x 30 ) / 390

= 13 / 30

= 13

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 819, 676, 30, 447 is 1
