Given numbers are 128, 684, 798, 789

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

Apply this formula for all numbers.

Step1:

LCM(128, 684) = 21888

GCD(128, 684) = ( 128 x 684 ) / 21888

= 128 / 684

= 128

Step2:

LCM(4, 798) = 1596

GCD(4, 798) = ( 4 x 798 ) / 1596

= 4 / 798

= 4

Step3:

LCM(2, 789) = 1578

GCD(2, 789) = ( 2 x 789 ) / 1578

= 2 / 789

= 2

So, Greatest Common Divisor of 128, 684, 798, 789 is 1
