Given numbers are 489, 693, 851, 385

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

Apply this formula for all numbers.

Step1:

LCM(489, 693) = 112959

GCD(489, 693) = ( 489 x 693 ) / 112959

= 489 / 693

= 489

Step2:

LCM(3, 851) = 2553

GCD(3, 851) = ( 3 x 851 ) / 2553

= 3 / 851

= 3

Step3:

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

= 1 / 385

= 1

So, Greatest Common Divisor of 489, 693, 851, 385 is 1
