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

Apply this formula for all numbers.

Step1:

LCM(168, 792) = 5544

GCD(168, 792) = ( 168 x 792 ) / 5544

= 168 / 792

= 168

Step2:

LCM(24, 646) = 7752

GCD(24, 646) = ( 24 x 646 ) / 7752

= 24 / 646

= 24

Step3:

LCM(2, 676) = 676

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

= 2 / 676

= 2

So, Greatest Common Divisor of 168, 792, 646, 676 is 2
