Given numbers are 545, 789, 645

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

Apply this formula for all numbers.

Step1:

LCM(545, 789) = 430005

GCD(545, 789) = ( 545 x 789 ) / 430005

= 545 / 789

= 545

Step2:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 545, 789, 645 is 1
