Given numbers are 621, 891, 298, 819

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

Apply this formula for all numbers.

Step1:

LCM(621, 891) = 20493

GCD(621, 891) = ( 621 x 891 ) / 20493

= 621 / 891

= 621

Step2:

LCM(27, 298) = 8046

GCD(27, 298) = ( 27 x 298 ) / 8046

= 27 / 298

= 27

Step3:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

So, Greatest Common Divisor of 621, 891, 298, 819 is 1
