Given numbers are 645, 393, 382, 789

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

Apply this formula for all numbers.

Step1:

LCM(645, 393) = 84495

GCD(645, 393) = ( 645 x 393 ) / 84495

= 645 / 393

= 645

Step2:

LCM(3, 382) = 1146

GCD(3, 382) = ( 3 x 382 ) / 1146

= 3 / 382

= 3

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 645, 393, 382, 789 is 1
