Given numbers are 819, 420, 776, 874

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

Apply this formula for all numbers.

Step1:

LCM(819, 420) = 16380

GCD(819, 420) = ( 819 x 420 ) / 16380

= 819 / 420

= 819

Step2:

LCM(21, 776) = 16296

GCD(21, 776) = ( 21 x 776 ) / 16296

= 21 / 776

= 21

Step3:

LCM(1, 874) = 874

GCD(1, 874) = ( 1 x 874 ) / 874

= 1 / 874

= 1

So, Greatest Common Divisor of 819, 420, 776, 874 is 1
