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

Apply this formula for all numbers.

Step1:

LCM(768, 392) = 37632

GCD(768, 392) = ( 768 x 392 ) / 37632

= 768 / 392

= 768

Step2:

LCM(8, 306) = 1224

GCD(8, 306) = ( 8 x 306 ) / 1224

= 8 / 306

= 8

Step3:

LCM(2, 656) = 656

GCD(2, 656) = ( 2 x 656 ) / 656

= 2 / 656

= 2

So, Greatest Common Divisor of 768, 392, 306, 656 is 2
