Given numbers are 789, 689, 384, 657

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

Apply this formula for all numbers.

Step1:

LCM(789, 689) = 543621

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

= 789 / 689

= 789

Step2:

LCM(1, 384) = 384

GCD(1, 384) = ( 1 x 384 ) / 384

= 1 / 384

= 1

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 789, 689, 384, 657 is 1
