Given numbers are 676, 388, 908, 643

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

Apply this formula for all numbers.

Step1:

LCM(676, 388) = 65572

GCD(676, 388) = ( 676 x 388 ) / 65572

= 676 / 388

= 676

Step2:

LCM(4, 908) = 908

GCD(4, 908) = ( 4 x 908 ) / 908

= 4 / 908

= 4

Step3:

LCM(4, 643) = 2572

GCD(4, 643) = ( 4 x 643 ) / 2572

= 4 / 643

= 4

So, Greatest Common Divisor of 676, 388, 908, 643 is 1
