Given numbers are 816, 530, 856, 389

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

Apply this formula for all numbers.

Step1:

LCM(816, 530) = 216240

GCD(816, 530) = ( 816 x 530 ) / 216240

= 816 / 530

= 816

Step2:

LCM(2, 856) = 856

GCD(2, 856) = ( 2 x 856 ) / 856

= 2 / 856

= 2

Step3:

LCM(2, 389) = 778

GCD(2, 389) = ( 2 x 389 ) / 778

= 2 / 389

= 2

So, Greatest Common Divisor of 816, 530, 856, 389 is 1
