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

Apply this formula for all numbers.

Step1:

LCM(789, 178) = 140442

GCD(789, 178) = ( 789 x 178 ) / 140442

= 789 / 178

= 789

Step2:

LCM(1, 43) = 43

GCD(1, 43) = ( 1 x 43 ) / 43

= 1 / 43

= 1

So, Greatest Common Divisor of 789, 178, 43 is 1
