Given numbers are 819, 984, 243, 842

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

Apply this formula for all numbers.

Step1:

LCM(819, 984) = 268632

GCD(819, 984) = ( 819 x 984 ) / 268632

= 819 / 984

= 819

Step2:

LCM(3, 243) = 243

GCD(3, 243) = ( 3 x 243 ) / 243

= 3 / 243

= 3

Step3:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

So, Greatest Common Divisor of 819, 984, 243, 842 is 1
