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

Apply this formula for all numbers.

Step1:

LCM(789, 711) = 186993

GCD(789, 711) = ( 789 x 711 ) / 186993

= 789 / 711

= 789

Step2:

LCM(3, 989) = 2967

GCD(3, 989) = ( 3 x 989 ) / 2967

= 3 / 989

= 3

So, Greatest Common Divisor of 789, 711, 989 is 1
