Given numbers are 789, 663, 135, 392

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

Apply this formula for all numbers.

Step1:

LCM(789, 663) = 174369

GCD(789, 663) = ( 789 x 663 ) / 174369

= 789 / 663

= 789

Step2:

LCM(3, 135) = 135

GCD(3, 135) = ( 3 x 135 ) / 135

= 3 / 135

= 3

Step3:

LCM(3, 392) = 1176

GCD(3, 392) = ( 3 x 392 ) / 1176

= 3 / 392

= 3

So, Greatest Common Divisor of 789, 663, 135, 392 is 1
