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

Apply this formula for all numbers.

Step1:

LCM(309, 291) = 29973

GCD(309, 291) = ( 309 x 291 ) / 29973

= 309 / 291

= 309

Step2:

LCM(3, 717) = 717

GCD(3, 717) = ( 3 x 717 ) / 717

= 3 / 717

= 3

Step3:

LCM(3, 783) = 783

GCD(3, 783) = ( 3 x 783 ) / 783

= 3 / 783

= 3

So, Greatest Common Divisor of 309, 291, 717, 783 is 3
