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

Apply this formula for all numbers.

Step1:

LCM(809, 121) = 97889

GCD(809, 121) = ( 809 x 121 ) / 97889

= 809 / 121

= 809

Step2:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

So, Greatest Common Divisor of 809, 121, 81 is 1
