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

Apply this formula for all numbers.

Step1:

LCM(648, 330) = 35640

GCD(648, 330) = ( 648 x 330 ) / 35640

= 648 / 330

= 648

Step2:

LCM(6, 392) = 1176

GCD(6, 392) = ( 6 x 392 ) / 1176

= 6 / 392

= 6

Step3:

LCM(2, 676) = 676

GCD(2, 676) = ( 2 x 676 ) / 676

= 2 / 676

= 2

So, Greatest Common Divisor of 648, 330, 392, 676 is 2
