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

Apply this formula for all numbers.

Step1:

LCM(819, 243) = 22113

GCD(819, 243) = ( 819 x 243 ) / 22113

= 819 / 243

= 819

Step2:

LCM(9, 768) = 2304

GCD(9, 768) = ( 9 x 768 ) / 2304

= 9 / 768

= 9

Step3:

LCM(3, 798) = 798

GCD(3, 798) = ( 3 x 798 ) / 798

= 3 / 798

= 3

So, Greatest Common Divisor of 819, 243, 768, 798 is 3
