Given numbers are 789, 154, 605, 859

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

Apply this formula for all numbers.

Step1:

LCM(789, 154) = 121506

GCD(789, 154) = ( 789 x 154 ) / 121506

= 789 / 154

= 789

Step2:

LCM(1, 605) = 605

GCD(1, 605) = ( 1 x 605 ) / 605

= 1 / 605

= 1

Step3:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 789, 154, 605, 859 is 1
