Given numbers are 622, 389, 81

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

Apply this formula for all numbers.

Step1:

LCM(622, 389) = 241958

GCD(622, 389) = ( 622 x 389 ) / 241958

= 622 / 389

= 622

Step2:

LCM(1, 81) = 81

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

= 1 / 81

= 1

So, Greatest Common Divisor of 622, 389, 81 is 1
