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

Apply this formula for all numbers.

Step1:

LCM(689, 789) = 543621

GCD(689, 789) = ( 689 x 789 ) / 543621

= 689 / 789

= 689

Step2:

LCM(1, 555) = 555

GCD(1, 555) = ( 1 x 555 ) / 555

= 1 / 555

= 1

So, Greatest Common Divisor of 689, 789, 555 is 1
