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

Apply this formula for all numbers.

Step1:

LCM(978, 342) = 55746

GCD(978, 342) = ( 978 x 342 ) / 55746

= 978 / 342

= 978

Step2:

LCM(6, 765) = 1530

GCD(6, 765) = ( 6 x 765 ) / 1530

= 6 / 765

= 6

Step3:

LCM(3, 591) = 591

GCD(3, 591) = ( 3 x 591 ) / 591

= 3 / 591

= 3

So, Greatest Common Divisor of 978, 342, 765, 591 is 3
