Given numbers are 306, 765, 321

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

Apply this formula for all numbers.

Step1:

LCM(306, 765) = 1530

GCD(306, 765) = ( 306 x 765 ) / 1530

= 306 / 765

= 306

Step2:

LCM(153, 321) = 16371

GCD(153, 321) = ( 153 x 321 ) / 16371

= 153 / 321

= 153

So, Greatest Common Divisor of 306, 765, 321 is 3
