Given numbers are 789, 520, 869

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

Apply this formula for all numbers.

Step1:

LCM(789, 520) = 410280

GCD(789, 520) = ( 789 x 520 ) / 410280

= 789 / 520

= 789

Step2:

LCM(1, 869) = 869

GCD(1, 869) = ( 1 x 869 ) / 869

= 1 / 869

= 1

So, Greatest Common Divisor of 789, 520, 869 is 1
