Given numbers are 489, 777, 380, 823

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

Apply this formula for all numbers.

Step1:

LCM(489, 777) = 126651

GCD(489, 777) = ( 489 x 777 ) / 126651

= 489 / 777

= 489

Step2:

LCM(3, 380) = 1140

GCD(3, 380) = ( 3 x 380 ) / 1140

= 3 / 380

= 3

Step3:

LCM(1, 823) = 823

GCD(1, 823) = ( 1 x 823 ) / 823

= 1 / 823

= 1

So, Greatest Common Divisor of 489, 777, 380, 823 is 1
